I will work on matching to Mozilla's and track individual items in subtickets.

It complained when you had CMake in your path, or when you didn't?  Something I got tripped up by was building in a MinGW prompt vs a normal command prompt.  In my "simplest reproduction" phase, I found I could build straight from a windows command prompt if CMake was in my path.

Hm.  I'll see if I can find time to test more tomorrow: that crash is in xul.dll!JSD_GetValueForObject whereas mine is in xul!ReteNodeSet::Iterator::operator*+0xa

Also, mine occurs on startup, I can't even get the browser loaded enough to see the application.
