is working fine. I don't have any idea what is going on. Any idea as to why this is happening? git cygwin git-extensions share|improve this question asked Aug 29 '13 at 5:33 Uchia Itachi 2,7002915 3 Cygwin is weird and uses persistent shared memory sections. Have you tried rebooting your system? –Greg Hewgill Aug 29 '13 at 5:38 @GregHewgill: Haven't rebooted since few days. Will do it right away. –Uchia Itachi Aug 29 '13 at 5:40 1 @GregHewgill: It worked out. Thanks, maybe if you post it as an answer it will be helpful for others too. –Uchia Itachi Aug 29 '13 at 5:58 Just wanted to say that this bug isn't specific to git and on bad days cygwin will crash on any executable in the same way for no apparent reason. –meneldal Jun 9 '15 at 5:22 add a comment| 11 Answers 11 active oldest votes up vote 173 down vote accepted Cygwin uses persistent shared memory sections, which can on occasion become corrupted. The symptom of this is that some Cygwin programs begin to fail, but other applications are unaffected. Since these shared memory sections are persistent, often a system reboot is needed to clear them out before the problem can be resolved. share|improve this answer edited Nov 4 '15 at 9:15 Dyin 4,60842545 an

It's Cygwin code failing to allocate a ~5 MB large chunk of memory for its heap at this fixed address 0x68570000, while only a hole win32 error ~2.5 MB large was apparently available there. The relevant code can be seen inmsysgit source. Resolution Bothcurrent Cygwinand thenew version of MSYS- MSYS2 - already have different logic in place, which is hopefully more robust. It's only old versions of Git for Windows which have been still built using the win32 error 487 old broken MSYS system. Resolution: InstallGit for Windows 2- it is built with the new,properly maintained MSYS2and also has many new features, plenty of bug fixes and so on. There is also a 64-bit version available which would lower the chance of address space clashes considerably even if this problem was not fixed. On ourSupported Platformswe outline the Git versions that should work well with your environment. Was this helpful? Yes No Thanks for your feedback! Why was this unhelpful?
