#22943 [Opn]: "Problem with method call" segfault

ID: 22943 User updated by: dubious at 2xtreme dot net Reported By: dubious at 2xtreme dot net Status: Open Bug Type: Reproducible crash Operating System: Linux (2.5.66) PHP Version: 4.3.2RC1 New Comment: P.S. The problem appears to be that I am an idiot :-) I mistakenly typo'd and had the method calling ITSELF rather than the other, similarly-named method I had intended. In other words, I caused this myself with an accidentally-infinitely-recursive function. Unless there is any reasonable way to expect the PHP interpreter to "catch" stupid things like this (or show and error that describes more accurately what the problem might be?), it's probably worth just marking this bug "bogus" and deleting all records of it to avoid further embarassment of myself... Previous Comments: ------------------------------------------------------------------------ [2003-03-28 18:14:26] dubious at 2xtreme dot net Quick update - don't know if it matters, but if I remove the "--disable-cgi" the error messages disappear...but it still segfaults. (I assume this is just the CGI version suppressing the error message to keep from cluttering web displays?) ------------------------------------------------------------------------ [2003-03-28 17:31:01] dubious at 2xtreme dot net Not sure where to start with this one - I'm getting an unexplained segfault while running a script I'm in the middle of trying to debug. The error states "PHP Warning: Problem with method call - please report this bug in /root/projects/biophp_code/clustal_parser_class.php on line 48 PHP Fatal error: Call to a member function on a non-object in /root/projects/biophp_code/clustal_parser_class.php on line 49 Segmentation fault" You can find a tarball of the relevant files, plus the output from strace, in the tarball at http://www.dogphilosophy.net/~biophp/php_clustal_crash.tar.bz2 The script I'm running is "clustal_parser_test.php" Note I went back and recompiled 4.3.1 and 4.3.0, and both also exhibit the same problem... In case it's helpful, the output from php -i is: PHP Version => 4.3.2-RC1 System => Linux enzymestew 2.5.66 #2 Mon Mar 24 22:58:05 MST 2003 i686 Build Date => Mar 25 2003 15:20:43 Configure Command =>
