But it should be a debug build. Well a build with debug symbols (not a
firefox-style debug which adds also a lot of debug code).
I add:
ac_add_options --disable-strip
and this helps on Linux usually.
If the binary was stripped, you wouldn't see any names, just addresses.
To see line numbers, you have to build with -g, and the DWARF
information has to be available at runtime, by default in the build
directory in .dSYM bundles.
Still, the nsWindowWatcher class gave me a clue and I found a couple of
Firefox patches to import which initialized parameters, checked them,
etc.... and now the error changed to>

this is bad, since it is inside the JS engine. Also the JS engine works
on other system when compiled with modern clang and gcc!
Also here I don't have a class name which maps directly to a file which
I can easily inspect.
Looks like its defined in js/public/RootingAPI.h ?
