This happens if the app that hosts WebKit calls fork() for whatever reason. This is a problem because I enjoy calling fork() often. Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000 Thread 0 Crashed: 0 <<00000000>> 0x00000000 0 + 0 1 libSystem.B.dylib 0x900323cc fork + 44 3046 1 mrowe 2007-08-03 14:29:16 -0700 Fork you! The issue here is that I left some of the "unused" malloc zone functions nulled out. Looks like they're not unneeded after all :) The fix here is to provide no-op stubs rather than leaving the function pointers null. 3028 2 mrowe 2007-08-03 14:43:23 -0700 <rdar://problem/5385145> 3002 3 mrowe 2007-08-04 02:02:50 -0700 Fixed in r24868.
