git svn fetch/rebase error: unable to remap msys-ssl-0.9.8.dll to same address as parent -- 0x678F0000

Question

I recently started getting the following git error on git svn fetch or git svn rebase, but other local git commands are working fine:

Following is the detailed error message:

C:\Git\bin\perl.exe: ** unable to remap C:\Git\bin\msys-ssl-0.9.8.dll to same address as parent -- 0x678F0000
      0 [main] perl 1300 sync_with_child: child 7092(0x324) died before initialization with status code 0x1
    567 [main] perl 1300 sync_with_child: *** child state child loading dlls

Environment:

• git version 1.8.5.2.msysgit.0
• OS: Windows7 64 bit
• SVN: 1.8.4-SlikSvn-1.8.4-X64
• Cygwin: I don't have cygwin installed on my machine
• Path: C:\Program Files (x86)\RSA SecurID Token Common;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files (x86)\Enterprise Vault\EVClient\;C:\Program Files (x86)\1E\SMSNomad\;C:\Pro gram Files (x86)\WinMerge;C:\work\tools\SlikSvn\bin;C:\Program Files\TortoiseSVN\bin;

I have tried multiple solutions including upgrading mysysgit from 1.8.2 to latest 1.8.5.2 but no luck yet.

I've experienced that several times myself. I don't know how to fix it, but the error disappeared for me when I tried it again at later time. – Mastoiditis

@Mastoiditis - I am getting this error since past 2 days, and multiple reboots didn't solved this issue as well. Do you remember installing/uninstalling anything which may have fixed this issue? – Foretooth

@Mastoiditis - you were right! All of the sudden problem is fixed and I can fetch/rebase now :) – Foretooth

I suddenly encountered this problem with mysgit 1.9.4 after months of it working correctly. I updated to 2.5.3 and it started working again. – Panatella

Answer 1

The root cause of this issue and any variants of it is two DLLs have been mapped to the same address, causing a conflict. Individual cases can be solved using rebase.

Msysgit 1.9.4-preview20140815 contains a case of this issue with the libsvn_repos-1-0.dll and libneon-25.dll libraries. Using the command git svn gives a similar error message as described in the question.

The bug report contains this workaround:

Rebase to free regions via: (execute as Administrator)

rebase -b 0x64000000 bin/libsvn_repos-1-0.dll
rebase -b 0x64200000 bin/libneon-25.dll

After this git svn works correctly.

Other cases should be solvable in a similar manner, choosing free addresses for the DLLs with which the issue occurs.

This worked for me, although if your environment is like mine you will just specify "libneon-25.dll" not "bin/libneon-25.dll" – Otero

Thanks heaps. Git is useless without Stackoverflow and good souls like yourself. – Cundiff

rebase.exe the bin directory (bin\rebase.exe) of msysgit/git-for-windows, should anyone wondering. – Decoupage

For me, the rebase command itself is giving me the same error. Any one can help? – Ridgeway

Worked for me. Initially I was getting "failed with last error = 6" for the rebase commands. After ensuring no other processes were using the DLLs (killing all perl.exe processes started with SourceTree) the commands worked as expected. – Sphygmic

Answer 2

Not the best answer, but a reboot fixed it for me.

Seems related to this issue, so probably address-space related.

Appreciated your response! Unfortunately even multiple reboots didn't solved this issue for me. – Foretooth

Answer 3

I had a same problem with git 1.9.4-preview20140815 on Windows Server 2008 R2. Restarts didn't help.

I have downgraded git to version 1.8.1.2-preview20130201 and it solved a problem.

Answer 4

Just try to uninstall mysysgit and re-install it. For my case this resolved the issue.

Answer 5

I had the similar issue and i tried restarting my machine but it didn't work. It worked when I downgraded GIT to 1.8.5.2.

Answer 6

Same issue, all rebasing of dll-addresses did not work for me. Now 'Git Svn' works for me again. Following steps solved the problem (Git 1.9):

1) Deinstall

2) Reboot

3) Install of most recent git version (2.7)

Answer 7

I had a similar problem on a system with git 1.9.5.msysgit.0.

The dll reported in the error for me was libsvn_swig_perl-1-0.

The exact error was:
C:\Git\bin\perl.exe: *** unable to remap C:\Git\bin\libsvn_swig_perl-1-0.dll to same address as parent -- 0x667B0000

On my system the original base address of Git\bin\libsvn_swig_perl-1-0.dll was 0x666C0000 (666C0000 to 66790FFF).

I managed to solve the problem with a rebase -b 0x667C0000 libsvn_swig_perl-1-0.dll from within the Git\bin directory (that 0x667C0000 is my original base plus a random 0x00100000).

---

One way to see the current base address of a dll is with dumpbin /headers.

I had the same issue. Restart didn't help, downgrade didn't help, but I made git reset --hard and it work now.

I know it was side-effect, but if someone is desperate like I was...
