PHP regular expression functions fail on GoDaddy shared hosting

While testing some crawler script on GoDaddy shared hosting I noticed that the script is quitting w/o any notice at random points. Both web and CLI execution modes where affected. The script was previously tested on XAMPP server where it  worked fine.

Lately, I identified that script always quits after calling one of regular expression functions (PRCE) like preg_replace, preg_match and preg_match_all. The script called them hundreds of times and one of the calls became fatal.

UPDATE: Actually it appears to be some kind of general problem with long string operations. But switching to multi-byte string regular expression functions helped in most scenarios.
