I don't see any difference assuming that ZTS is disabled.
Jan, do you use IRC? It's incovenient to talk using the bugtracker.

This works fine. But I'm loading httpd when debugging segfaults.

Try this:
gdb php
b zif_var_dump
r -r 'var_dump(1);'
p
(char*)(executor_globals.function_state_ptr->function)->common.function_name

I never, ever made a ZTS build of PHP in my whole life. And just to be
sure, I verified with phpinfo().
Anything else I could check? I don't know my way through gdb, I only
use it for generating backtraces. Is there a way to list the available
symbols?

Well, it looks like you did enable it, because it works perfectly fine
here:

Breakpoint 1, zif_var_dump (ht=1, return_value=0x836c1ac,
return_value_ptr=0x0, this_ptr=0x0, return_value_used=0) at
/local/dev/php/5_2/ext/standard/var.c:177
177             argc = ZEND_NUM_ARGS();
(gdb) print
(char*)(executor_globals.function_state_ptr->function)->common.function_name
$1 = 0x829c56b "var_dump"

No, it's a debug non-zts linux build.
