Hi! ----
Running the git testsuite I got a hang of the "t1004-read-tree-m-u-wf.sh" test in Cygwin 3.7 - the same test worked AFAIK OK with Cygwin 3.5.x. My guess: |wait_sig()| and |_sigfe()| are involved, maybe this is a signal issue.. 1. Versions: Cygwin 3.7.0-0.68.g37c49decc835.x86_64 / Windows 10 2. Steps to reproduce: ---- snip ---- mkdir gittest cd gittest/ git clone -b 'v2.45.1' https://github.com/git/git.git cd git autoconf automake CC="gcc -std=gnu17" ./configure time make -j4 all time nice make -i test ---- snip ---- Process "git merge-recursive branch-point -- side-b side-a" launched by "/bin/sh t1004-read-tree-m-u-wf.sh" hangs forever with this stack trace: ---- snip ---- (gdb) thread apply all bt Thread 4 (Thread 8148.0xb64): #0 0x00007ffe68f91021 in ntdll!DbgBreakPoint () from /cygdrive/c/Windows/SYSTEM32/ntdll.dll #1 0x00007ffe68fbca7e in ntdll!DbgUiRemoteBreakin () from /cygdrive/c/Windows/SYSTEM32/ntdll.dll #2 0x00007ffe66f17374 in KERNEL32!BaseThreadInitThunk () from /cygdrive/c/Windows/System32/KERNEL32.DLL #3 0x00007ffe68f3cc91 in ntdll!RtlUserThreadStart () from /cygdrive/c/Windows/SYSTEM32/ntdll.dll #4 0x0000000000000000 in ??
