#168 fixed Arora web browser crashes in LIBC rudi

When surfing around Arora often crashes with the following register dump:

It's an attempt to "setmem" a NULL pointer. I tried to analyze the problem and to me it appears that this comes from /webkit/JavaScriptCore/runtime/Collector.cpp, line 273. Digging a bit into the implementation of posix_memalign() in KLIBC, I tend to think that this function will not work correctly, when the requested alignment is larger than a page size. But exactly this happens in line 272.

I suggest to modify JavaScriptCore?\wtf\platform.h so that for OS/2 HAVE_POSIX_MEMALIGN is zero. Note that there are two instances of the JavaScriptCore? in the 3rdparty subtree: one that goes into QtScript? and one that ends up in QtWebKit?.

At the moment I'm writing this, my finding is just a hypothesis. I will try to prove it, when my other builds are complete...

#148 invalid Assistant doesn't work anymore rudi

With the latest trunk, Assistant quit. The program just exists without showing even the slightest traces of a window. Just started a debug build. Maybe this will give some idea what might be wrong...
