#38449 [Fbk->Csd]: Segfault when token_get_all is used

ID: 38449 User updated by: scottmacvicar at ntlworld dot com Reported By: scottmacvicar at ntlworld dot com -Status: Feedback +Status: Closed Bug Type: Reproducible crash Operating System: FreeBSD 4.10-RELEASE-p5 PHP Version: 4.4.3 New Comment: I edited the ports Makefile to add --enable-tokenizer and removed the tokenizer as an extension and there was no crash. I tried a similar setup on my debian box following the same procedure with tokenizer as an extension and had no problem. I'm going to look a little closer later on and see if I can identify what in particular is causing this on the FreeBSD box.
