It seems the problem is in... http://mxr.mozilla.org/mozilla-central/source/gfx/cairo/libpixman/src/pixman-pict.c lines 2031 and 2032 seem to be corrupted resulting in armv6 code attempting to run on the emulator (armv4)

This is different than bug 478159, how ever it does block it.

Does this still happen? The lines mentioned above look correct to me, as does the rest of the detection code now. Also, the WinCE paths will probably want something like http://hg.mozilla.org/releases/mozilla-1.9.2/rev/be6c505a2003 to suppress reporting the illegal instructions to the debugger when we try to execute them. Assigning to jeff to do as he wishes!
