Summary: Regular expression tests: SEGV on Mac OS
Initial Comment:
The regular expression regression tests 'test_re'
causes a SEGV failure on Mac OS X version 10.0.1
when using Python 2.1c2 (and earlier). This is
caused by the test trying to recurse 50,000 levels
deep.
Workaround: A workaround is to limit how deep the
regular expression library can recurse (this is
already done for Win32). This can be achieved by
changing file './Modules/_sre.c' using the following
patch:
--- ./orig/_sre.c Sun Apr 15 19:00:58 2001
+++ ./new/_sre.c Mon Apr 16 21:39:29 2001
