I've already enabled coredumping when I sent the original bug report.
Since then there was a single SIGFPE crash that did not produce a core
dump, and a second one, now SIGSEGV, that indeed looks like a PHP
bug (backtrace below). It may be that there are actually two bugs...
Core was generated by `/usr/sbin/apache2 -k start'.
Program terminated with signal 11, Segmentation fault.
