I recompiled php 4.0.6 with enable-debug. Now I see this in logs:
preparser-scanner.l(450) : Freeing 0x0820547C (249 bytes),
script=/usr/local/apache/libexec/midgard-root.php
Last leak repeated 14 times
midgard.c(440) : Freeing 0x081624C4 (12 bytes),
script=/usr/local/apache/libexec/midgard-root.php
ran gdb again and got this when I hit the nadmin page
