segfaults with zendplatform/debugger

Hello, since yesterday I have retried to use zendplatform and it's debugger together with zend studio. (PHP Version is 5.1.6, happened with 5.1.4 too) We are getting a reproducable segmentation fault as follows: Program received signal SIGSEGV, Segmentation fault. 0xb79c37db in zend_get_zval_ptr_ptr () from /usr/lib/apache2/modules/libphp5.so (gdb) where #0 0xb79c37db in zend_get_zval_ptr_ptr () from /usr/lib/apache2/modules/libphp5.so #1 0xb79b0249 in execute () from /usr/lib/apache2/modules/libphp5.so #2 0xb7981e7e in execute () from /usr/lib/apache2/modules/libphp5.so #3 0xb5c7210f in ?? () from /opt/Zend/lib/Debugger-5.2.0/php-5.1.x/ZendDebugger.so #4 0x0865432c in ?? () #5 0x00000001 in ?? () #6 0x00000000 in ?? () Can not get out more information since zendplatform does not run when php is compiled with --enable-debug. The script I run through the debugger is: <? $pid = getmypid(); echo($pid); ?> The debugger has a "watch" for a "$this->foo" entry. With this watch setting it always crashes PHP in line 3 (the echo...). (yes, I know I do not have an object in this code but this is not a reason to segfault ;) Is this a zendplatform issue or php zend engine issue? Where do you think I should schedule a bug entry?
