Hello,
 
With the latest Cygwin-DLL and C/C++ developer packages I am experiencing issues to run self-compiled programs.
I prepared an example using the grep-Package
 
grep-3.7-2 from your GIT-repo
and compiled using "cygport"
 
The linked binary grep.exe crashes
 
 
It appears to me that there is an issue with threading. Building grep without thread-usage makes it runnable.
 
Unfortunately, I didn't get any usable stack-trace.
 
Maybe the newer binutils require additional compiler flags, those haven't been provided yet?
 
Thanks.
