I'm experiencing a core dump when macroizing a portion of a DX
network. DXUI writes the macro successfully, but then saving the modified
network yields a SEGV before it completes.
Running a purified dxui executable yields no errors except a few FMMs
before the core dump. Those FMMs occur while saving the modified network.
I'd sure appreciate it if someone who knows DX internals could take a
quick glance and give me your impression.
Thanks,
Randall Hopper
