Hi,
I am receiving a segfault when trying to generate code for a valuetype.
I think it has something to do with the valuetype supporting an
interface that is an alias.
I have isolated the problem using the two idl files attached. You can
reproduce it running "idl -I. myidl2.idl".
I also attached a patch that tries to solve the problem, but I am not
sure about it's correctness. Can you please take a look?
The gdb backtrace shows this:
Program received signal SIGSEGV, Segmentation fault.
