ibase_close function causes Segmentation fault (11) in Apache 1.3.23 web server.


Program received signal SIGSEGV, Segmentation fault.
0x40430c7c in memcpy () from /lib/i686/libc.so.6
(gdb) bt
#0  0x40430c7c in memcpy () from /lib/i686/libc.so.6
#1  0x00000000 in __strtol_internal (nptr=0x0, endptr=0x0, base=165,
group=128)

If I comment out the ibase_close() from my PHP scripst all works well.

Can you provide more context of the backtrace (e.g. a few more lines from 'bt full') ?
 [2002-03-11 06:25 UTC] office at lunar dot com dot pl 
No symbol table info available.

What else can I do to help?
 [2002-03-11 06:33 UTC] [email protected] 
Recompile php and the module (if not static already) with the configure line '--enable-debug'.
 [2002-03-11 06:51 UTC] office at lunar dot com dot pl 
As before i did:

./configure --without-mysql --with-imap --with-imap-ssl --with-interbase --with-pgsql --with-kerberos --with-gettext --with-xml --with-apache=../apache_1.3.23/ --enable-track-vars --enable-debug > .log

Backtrace only outputs the same 2 lines after httpd crashes

Try compiling Apache with --enable-debug too.
 [2002-03-11 09:32 UTC] office at lunar dot com dot pl 
Apache does not have en --enable-debug option but I compiled it with -g option in gcc and it still did not work.
I only get 2 lines of backtrace info :(

Fixed in today CVS (4.3.0-dev)

same as bug #15419 - #14558
