Re: bash exits when test or [ ] is used in Windows Server 2008


I can't reproduce this issue on a fresh install of Windows 2008 in a virtual 
machine using terminal server, I supppose it should just work but it doesn't.

When I start test or [ ] a stackdump is created with the following information:
Exception: STATUS_ACCESS_VIOLATION at eip=775D9832

Please note everything seems to work except [ ] and test in bash (the internal 
version! not /usr/bin/[ or /usr/bin/test)

I've also disable DEP for applications which doesn't help either.

cygcheck -srv doesn't find duplicate cygwin1.dll libraries, but it does find
HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin entries which aren't visible in regedit.exe.
I suppose this is caused by virtual registry.

strace bash -c '[ ]' gives the following output:
