The also succeed on FreeBSD-5. On FreeBSD-4 some tests hang for ever all (or most) having to do with semaphores. >How-To-Repeat: Update to the very latest version of the devel/nspr port. Run: make build test Some tests at the beginning may take a while, but the first one to truly hang is nameshm1: (gdb) where #0 0x280cfeac in semsys () from /usr/lib/libc_r.so.4 #1 0x280c7122 in semop () from /usr/lib/libc_r.so.4 #2 0x80526d8 in PR_WaitSemaphore () #3 0x804c1d0 in ClientServerTest () #4 0x804c643 in main () #5 0x804b556 in _start () You can kill the hung ones (killall nameshm1) and allow the test harness to proceed to the next one (randseed): (gdb) where #0 0x280dcf38 in __sys_poll () from /usr/lib/libc_r.so.4 #1 0x280dc41d in _thread_kern_sched_state_unlock () from /usr/lib/libc_r.so.4 #2 0x280dbdd2 in _thread_kern_scheduler () from /usr/lib/libc_r.so.4 #3 0x0 in ?? () A thread-developer needs to look at this to either fix -lc_r, or point out the bugs in the NSPR or its self-tests. The tests are single-file C-programs in work/nspr-4.6/mozilla/nsprpub/pr/tests they are run from their build-area in work/nspr-4.6/mozilla/nsprpub/build/pr/tests/ Again, none of these problems exist on 5.x and, presumably, 6.x (except for the instrumt-test, which crashes on all and is currently patched-out from the list). >Fix: >Release-Note: >Audit-Trail: >Unformatted:
