New submission from Berker Peksag:
This is a follow-up from msg275748 in issue 27213 (Rework CALL_FUNCTION*
opcodes). I believe the test_runpy failure I mentioned there is also the same
error, but this one can be reproduced easily.
test_recursionlimit_fatalerror in SysModuleTest (Lib/test/test_sys.py)
segfaults on Ubuntu 12.04 (64-bit) with GCC 4.6.3. I compiled Python with the
following commands:
$ make distclean
$ ./configure --with-pydebug
$ make -s -j
To reproduce it, run (adapted from the test)
import sys
def f():
try:
f()
except RecursionError:
f()
sys.setrecursionlimit(10)
f()
I tried with different values like 50, 10, 1000 and the behavior is same.
In case it helps, here is the start of the backtrace:
