...Just FYI, I build a cygwin dll from current cvs (last winsup/cygwin/ChangeLog entry 2004-02-09 Ralf H.) with debugging enabled and rerun this script. It didn't freeze, I stopped it after 1588 iterations, but it produced one stackdump and wrote some errors from make to stderr:
$ ./t.sh > freeze.out
988627 [main] make 3376 handle_exceptions: Exception: STATUS_ACCESS_VIOLATION
996727 [main] make 3376 open_stackdumpfile: Dumping stack trace to make.exe.stackdump
make: *** virtual memory exhausted. Stop.
Volker
I tried using lates CVS too, here are the results:
Time to freeze: 761 and 409 iterations
This is MUCH better than before, but it still does freeze (althought a big difference now is that when make freezes, it consumes no CPU).
I'm speculating it has something to do with: "trying to send sig 20 but signal 20 already armed"
Here is an strace tail from the process that froze:
