Thanks for the hint. Fixed.

... which can be done by adding the packages as dependencies or via -Fu
in pas2js.cfg. You don't need to compile the packages as pas2js
compiles needed files automatically anyway.

The compiler does no DOM manipulations.
Delphi code would give an error message.
Not implemented feature would give an error message.

Can you compile the compiler from trunk and use gdb to get a backtrace?

Of course that is there. If you don't see any error it means something
