Running .exe in cygwin opens windows console with MapViewOfFileEx error, how do I fix this?

I'm trying to run programs I've compiled with GCC. When I run them through cygwin, a windows terminal opens for a couple of miliseconds (or so) giving off the error:

 fatal error - MapViewOfFileEx shared 5'(0x66). win32 error 6. Terminating

It's followed by a stack trace. (this was the best shot, had to use video camera)

It doesn't seem to affect the programs but since it's a "fatal error" I suppose it would be good to fix. I tried googling the error, and found that multiple cygwin1.dll in the path shown when running the command

cygcheck -s

could be the cause, but I only found 1 cygwin1.dll.

The problem could have come from when I tried to open a cygwin-created executeable in windows and I read that I should copy the cygwin1.dll into my windows-folder but I simply deleted it after realizing that I needed several more files (libraries).
