commit 24bffff63eb798d721b75b1c38c18f1687d33a2a Author: Corinna Vinschen <[email protected]> Date: Mon Nov 22 12:33:47 2021 +0100 Cygwin: raise: fix check for multithreaded process The check for the pthread self pointer in TLS is misleading, given the main thread has this pointer initialized as well. Check for the global __isthreaded flag as well.
