Summary: Failing test case for .*?
Initial Comment:
The following error is the result of patch 101612
Which tries to fix recursion limits in sre.
>>> s="""a\nb\n1"""
>>> re.findall("[^\n]+?\d", s)
['a\nb\n1']
A less than optimal work around makes sure a
simple '.' is being searched for.
If it has a chance of being accepted, I'll look for a
way to remove the recursion for more complex patterns.
line 1105 _sre.c
/* see if the tail matches */
state->repeat = rp->prev;
if (rp->pattern[2] == 65535 && (*(rp-
>pattern+3) == SRE_OP_ANY || *(rp->pattern+3) ==
SRE_OP_ANY_ALL)){
/* unbounded repeat */
for (;;) {
