Ok, got wine staging built off the 1.9.5 codebase, and I got the same error. I was able to test against an older version of the cygwin1.dll, and it didn't crash though. Maybe this is a cygwin bug? I don't know enough about either cygwin or wine to say whose problem this really is.
On the good side, it is dead simple to replicate.
I just retested 32 bit Wine Staging 1.9.4 + 32 bit Cygwin 2.4.1, and it works for me.
$ uname -a CYGWIN_NT-5.1 2.4.1(0.293/5/3) 2016-01-24 11:24 i686 Cygwin
Could you show `wine --version` and the new crash log?
