digitalmars.D.learn - Very vague compiler error message
- Jeremy DeHaan (7/7) Aug 12 2014 I recently got this error messege when building my library:

- Rikki Cattermole (5/12) Aug 12 2014 That error is being generated from within dmd itself.
- H. S. Teoh via Digitalmars-d-learn (6/15) Aug 12 2014 That's an ICE (Internal Compiler Error). Please reduce your test case
- Jeremy DeHaan (4/4) Aug 12 2014 Awesome, thanks everyone.

I recently got this error messege when building my library: dmd: cppmangle.c:154: void CppMangleVisitor::cpp_mangle_name(Dsymbol*): Assertion `0' failed. I have no idea what it means and haven't found much information about it. I think I have narrowed it down to the file that is giving this error, but does anyone know what the heck causes something like this? Talk about a nondescript error.

Talk about a nondescript error.That error is being generated from within dmd itself. In other words you've found an edge case congratulations! Look for functions/methods using the extern(C++) mangling. Mock them out into D versions and see which fails maybe?

Awesome, thanks everyone. I'll take the suggestion to use Dustmite as an excuse to familiarize myself with it, but if normally extern(C++) types cause it I know just where to look.

I didn't have access to my compute for longer than I thought, but
I finally got around to this.
After some messing around, I not only managed to track down the
cause, but I got it fixed and the Audio module for DSFML is back
to where it was.
In one of my D classes, SoundStream, I defined a struct called
Chunk, which held a chunk of sound data. It looks like this:
struct Chunk
{
const(short)* samples;
size_t sampleCount;
}
All of the streaming is actually happening in an extern(C++)
interface instance, and with the help of Dustmite, the method
that caused the initial error was this:
extern(C++) bool onGetData(SoundStream.Chunk* chunk);
I think because it has a D Class member as the parameter type in
an extern(C++) class method the D compiler broke?
What I did to fix it was I changed Chunk from being a member of
SoundStream and declared it as a extern(C++) struct instead.
That changed onGetData to "extern(C++) bool onGetData(Chunk*
chunk);" and the compiler was ok with that.
I might do some more testing to see if I can reproduce the error,
but changing the parameter type fixed it for me.
