While testing my print plugin, it segv'ed on me. The Gimp session is
still usable, although if I click on the Cancel button in the image I
tried to print the application exits. However, while the Gimp
continues running, it goes into a loop that consumes all the CPU
(about half system and half user). The truss output looks like this:
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN|POLLPRI},
{fd=8, events=POLLIN|POLLPRI, revents=POLLHUP}], 4, 44) = 1
gettimeofday({941590947, 150048}, NULL) = 0
ioctl(3, FIONREAD, [0]) = 0
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN|POLLPRI},
{fd=8, events=POLLIN|POLLPRI, revents=POLLHUP}], 4, 38) = 1
gettimeofday({941590947, 156848}, NULL) = 0
ioctl(3, FIONREAD, [0]) = 0
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN|POLLPRI},
{fd=8, events=POLLIN|POLLPRI, revents=POLLHUP}], 4, 31) = 1
gettimeofday({941590947, 163633}, NULL) = 0
ioctl(3, FIONREAD, [0]) = 0
The stack trace is something like this:
