As mentioned
https://cygwin.com/problems.html
"Run cygcheck -s -v -r > cygcheck.out and include that file as an
attachment in your report. Please do not compress or otherwise encode
the output. Just attach it as a straight text file so that it can be
easily viewed."
I have exactly the same results as Achim
./semtest.exe
Semaphore Test
Semaphore created successfully 65536
Value before errno = 0Semaphore 1492 initialized.
On both 32 and 64 bit.
So it seems a specific issue on your system side.
What software are you running ?
Any potential Bloda ?
