Thanks for the quick fix.

I tested a little bit but it doesn't work, and my patch to Wine still works.

Unfortunately it would be a bit tricky for me to provide a backtrace
very soon due to limited debug symbol support of WineDbg. Before look
deeper, could we confirm we are testing the same binary?

I'm testing:
 x86/cygwin1-20150401.dll.xz

$ sha1sum cygwin1-20150401.dll.xz
01d5092d48f3742cedcb28ea646b10088373d549  cygwin1-20150401.dll.xz

$ sha1sum cygwin1-20150401.dll
5619b74582a6584626c6dc05106698f9560d0d8a  cygwin1-20150401.dll

I renamed cygwin1-20150401.dll to  cygwin1.dll and copied to
C:\cygwin\bin\cygwin1.dll

But Wine bash.exe still crashes, in a slightly different way:
originally, it complains about access to invalid memory address
0x00000002, now it turns to invalid address 0x00000000 => not sure
this is useful information.

Here is some strace.exe output:

I can investigate deeper if that helps, maybe tomorrow.
