From @hvds

On a clang build this reduces to​:
% ./miniperl -e '$x = "(" x 957; /$x/'
Segmentation fault (core dumped)
%

With a gcc build I can increase that to around 3513 before it cores. It fails similarly with valid patterns​:
% ./miniperl -e '$re = ("(" x 3520) . (")" x 3520); /$re/'
Segmentation fault (core dumped)
%

I don't imagine we can do anything about that except to rewrite the regexp engine to further reduce the situations in which it recurses on the C stack, which I don't think is likely any time soon.
