Reassigned to Dmitry, he said he'll take a look at it along with other
memory manager related problems.

Thanks for the last hint, now I can replicate it.
It happens when an object is not initialized properly (because of the
memory limit).
Please give me some time, I'll try to find a solution..

No debug build.
It does not happen always, only if the memory gets
exhausted in line 8 ("$a = new stdClass;"), not if it gets
exhausted in a line like "$a->foo = rand(1000, 9999);".
Here's a backtrace from CLI:
Program received signal SIGSEGV, Segmentation fault.

Is your PHP build with --enable-debug? If it is on out-of-
memory error PHP dies with a segv.

There's only a sqlite related fix, if I do "cvs diff"?!
