Hmm. Cores are rerouted through syslog. Can you find an entry in /etc/syslog.conf that would match it? Just add '*' to the list of destinations, so it gets 'walled'. Enable mesg -y though.

I'm about to give up. I get this in syslog: Oct 31 11:13:20 sticky /kernel: pid 39069 (php), uid 0: exited on signal 11 (core dumped) So I look at the make test window: pid 39067 (php): unaligned access: va=0x12023ebbc pc=0x120191374 ra=0x120191368 op=stq pid 39067 (php): unaligned access: va=0x12023eadc pc=0x120191374 ra=0x120191368 op=stq pid 39069 (php): unaligned access: va=0x12023ebbc pc=0x120191374 ra=0x120191368 op=stq pid 39069 (php): unaligned access: va=0x12023eadc pc=0x120191374 ra=0x120191368 op=stq FAIL HTML input/output [ext/mbstring/tests/htmlent.phpt] Found it, right?

Program terminated with signal 11, Segmentation fault. warning: Hit heuristic-fence-post without finding warning: enclosing function for address 0x120029a08 This warning occurs if you are debugging a function without any symbols (for example, in a stripped executable). In that case, you may wish to increase the size of the search with the `set heuristic-fence-post' command.

Use CFLAGS='-O -pipe -fno-omit-frame-pointer' and --enable-debug to make sure that symbols are compiled in. If you've done so, the bug is in libc, and you should recompile the kernel with DEBUG options. Take a look at the LINT kernel in /sys/conf/$ARCH/.

That has been failing on 64-bit archs, a long time now :(

I guess it would be safe to label PHP 4.3.0 as "unsafe for 64-bit platforms!"? :(

THat's not a label we are looking to get, but currently the people who have the skills, don't have the systems so fixing these issues is kinda hard. Met vriendelijke groeten / With kind regards, Webmaster IDG.nl Melvyn Sopacua
