Follow-up Comment #18, bug#64806 (group make): Very strange. Looks like the parent process is waiting for the child to finish, and the child process cannot acquire the mutex and also waits.
Are all of the 8 sub-make's in the same situation? FWIW, I tried to run the Makefile you sent on my system, using my own MinGW32 build of Make 4.4.1, available here: https://sourceforge.net/projects/ezwinports/files/ and I cannot reproduce the hang, although I do see the "Cannot acquire output lock, disabling output sync" warnings a couple of times during the run. This is with GCC 9.2.0 on Windows XP, FTR. Perhaps also relevant: on my system cmp0 to cmp7 jobs run together (in parallel), whereas cmp8 and cmp9 run afterwards (in parallel with each other, but sequentially after cmp0-cmp7). Is this expected, given that I have a Core i7 machine with 4 cores and hyperthreading? _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64806> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
