I found this is caused by 'make' raising RLIMIT_STACK from the default setting of 8192k to its maximum, 65536k. It is reproducible from the shell by setting "ulimit -s 65536" before running the test program directly. I don't know if this is an eglibc bug or expected behaviour (and therefore a 'make' bug) so I am Cc'ing Petr. In the successful case, creation of each thread involves an mmap of len 0x800000 (8192k) by the parent: > pango1.0-1.36.0/debian/build/shared/tests$ ktrace -di -- > ./test-pangocairo-threads > 52374 100417 lt-test-pangocairo- CALL thr_new(0xffffc2ec,0x34) > 52374 100417 lt-test-pangocairo- RET thr_new 0 > 52374 100417 lt-test-pangocairo- CALL > mmap(0,0x800000,0x7<PROT_READ|PROT_WRITE|PROT_EXEC>,0x1002<MAP_ANON|MAP_TYPE|MAP_PRIVATE>,0xffffffff,0,0) > 52374 100417 lt-test-pangocairo- RET mmap 693108736/0x29500000 > 52374 100417 lt-test-pangocairo- CALL > mprotect(0x29500000,0x1000,0<PROT_NONE>) > 52374 100417 lt-test-pangocairo- RET mprotect 0 The failure case (when invoked by 'make') involves an mmap of len 0x4000000 instead (65536k) as each thread is created: > pango1.0-1.36.0/debian/build/shared/tests$ ktrace -di -- make check > 51903 100859 lt-test-pangocairo- CALL thr_new(0xffffc10c,0x34) > 51903 100859 lt-test-pangocairo- RET thr_new 0 > 51903 100859 lt-test-pangocairo- CALL > mmap(0,0x4000000,0x7<PROT_READ|PROT_WRITE|PROT_EXEC>,0x1002<MAP_ANON|MAP_TYPE|MAP_PRIVATE>,0xffffffff,0,0) > 51903 100859 lt-test-pangocairo- RET mmap 751828992/0x2cd00000 > 51903 100859 lt-test-pangocairo- CALL > mprotect(0x2cd00000,0x1000,0<PROT_NONE>) > 51903 100859 lt-test-pangocairo- RET mprotect 0 On kfreebsd-i386 only, this reproducibly fails at thread '53' of 100: > 51903 100859 lt-test-pangocairo- RET thr_new 0 > 51903 100859 lt-test-pangocairo- CALL > mmap(0,0x4000000,0x7<PROT_READ|PROT_WRITE|PROT_EXEC>,0x1002<MAP_ANON|MAP_TYPE|MAP_PRIVATE>,0xffffffff,0,0) > 51903 100859 lt-test-pangocairo- RET mmap -1 errno 12 Cannot allocate > memory > 51903 100859 lt-test-pangocairo- GIO fd 2 wrote 111 bytes > " > (process:51903): GLib-ERROR **: creating thread '53': Error creating > thread: Resource temporarily unavailable > " Regards, -- Steven Chamberlain ste...@pyro.eu.org -- To UNSUBSCRIBE, email to debian-bsd-requ...@lists.debian.org with a subject of "unsubscribe".
