Finally, I've managed to get a segfault when running erl -smp +S 1
(SMP with one core, like in your case). If the number of cores is
greater than one Erlang and wx work fine.

Could you try to run erl -smp +S 2 on your one-core processor to check
if this can be used as a workaround?

I'll forward this bug to upstream. Thanks for the report!

Cheers!
