not getting a segfault, but the symptoms seem similar -- program wedges
hard, window stops redrawing.
Ran the program with `strace mangler 2>/tmp/strace.log` and here's the
last system calls:
futex(0x98534cc, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 1, NULL, 0x985c528) = 0
clock_gettime(CLOCK_MONOTONIC, {1026549, 424232054}) = 0
write(17, "W", 1) = 1
clock_gettime(CLOCK_MONOTONIC, {1026549, 424536702}) = 0
write(17, "W", 1) = 1
futex(0x985c528, FUTEX_UNLOCK_PI_PRIVATE, 159724744) = 0
futex(0x98534cc, FUTEX_WAIT_REQUEUE_PI_PRIVATE, 3, NULL, 0x985c528) = 0
futex(0x985c528, FUTEX_UNLOCK_PI_PRIVATE, -1242918912) = 0
mmap2(NULL, 8392704, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_STACK,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
write(2, "\n(mangler:11131): glibmm-CRITICA"..., 195
(mangler:11131): glibmm-CRITICAL **:
unhandled exception (type Glib::Error) in signal handler:
domain: g_thread_error
code : 0
what : Error creating thread: Resource temporarily unavailable
) = 195
futex(0x9436900, FUTEX_WAIT_PRIVATE, 2, NULL
... and that's where the program waited until I gave it a Ctrl-C. No
troubles with the other programs (GTK+ and not) running at the same
time, so I'm confident it's not some resource pool for the entire
workstation being exhausted since the other GTK stuff doesn't crash nor
hang.
