No idea if this is helpful or even applies to your problem, but during the 
Haiku porting effort, we found out that when using USE_SYSTEM_MALLOC=1, 
WebCore makes some assumptions about alignment of allocations that are not 
guarenteed when using malloc() (should use memalign()). When we switched to 
using the built-in TCSystemMalloc, those problems went away.

Also, I don't know which build system you are using, but you need to make 
sure that you compile all parts of WebKit with the same defines. Since there 
are a lot of #defines in the code which enable or disable various features, 
the object sizes will change when you compile different parts of the code 
with different #defines, which can lead to all sorts of funny crashes.
