New submission from Orion Poplawski:
I'm seeing a segfault running the scipy 0.12 tests against numpy 1.7.1 with
python 3.3.1. The crash is here:
test_ticket_1645 (test_lapack.TestRegression) ...
Program received signal SIGSEGV, Segmentation fault.
PyErr_SetObject (exception=exception@entry=,
value=value@entry='On entry to SGERQF parameter number 7 had an illegal
value')
at /usr/src/debug/Python-3.3.1/Python/errors.c:67
67 exc_value = tstate->exc_value;
(gdb) print tstate
$1 = (PyThreadState *) 0x0
So it appears that PyThreadState_GET() is returning NULL and PyErr_SetOject()
is not handling that condition. Not sure if this is a sign of another issue.
(gdb) bt

it goes on a long ways down.
