I get this error when trying to clone a repository from either BitBucket or Github. I have tried restarting computer, reinstalling Sourcetree, but no luck. Any other tips? There is only one cygwin1.dll file on my computer.
0 [main] sh (8532) C:\Users\myUser\AppData\Local\Atlassian\SourceTree\git_local\usr\bin\sh.exe: *** fatal error - cygheap base mismatch detected - 0x1180400/0x1120400.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.
I installed GIT in windows and switched from embedded GIT to Windows GIT in SourceTree. Worked like a charm!
