Bug ID: 48931
           Summary: Any binary from 64bit Cygwin crashes on launch
           Product: Wine
           Version: 5.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Any binary from 64bit Cygwin crashes on launch with:

002b:err:seh:setup_exception stack overflow 8464 bytes in thread 002b eip
00007f77fc7784a1 esp 00000000ffff5500 stack 0xffe00000-0xffff7000-0x100000000

It happens only with 64bit Cygwin binaries. I can't reproduce it with 
32bit binaries.

It does not happen with the distribution Wine 5.0. But if I compile it from
source, it also crashes. It is always reproducible with Wine 5.6.

I was unsuccessful obtaining an useful backtrace so far but will continue
trying.

This bug is NOT about bash.exe terminating (see bug 48891) or binaries
crashing/terminating with FAST_CWD (see bug 40528).
