Given the following file header.as,

funcdef void functype();
shared class classname {}

and two separate script modules that are both loaded by the application, in this order,

#include "header.as"

#include "header.as"
classname classinstance;

my application consistently crashes when the modules are closed. (Pasting the contents of header.as into each module instead of using #include doesn't make any difference, but this felt clearer.) Removing any of the lines prevents the crash. Loading (and therefore probably closing) the modules in the other order prevents the crash.

Yes, discarding:

if (ASengine)
  while (ASengine->GetModuleCount())
    ASengine->GetModuleByIndex(0)->Discard();

They are separate modules, as I said. Multiple calls are made to CScriptBuilder::StartNewModule.

2.31.1.

ETA: I tried running the application in debug mode and got two asserts, I guess during compilation: asASSERT(func->objectType == intfType); at line 2541 of as_builder.cpp, and asASSERT((asUINT)intfFunc->vfTableIdx == j); at line 3002 of the same file.

Hmm. I think the crash is gone now, but I'm getting other asserts in a complicated set of circumstances... I'll let you know when I figure out what's going on/a minimal test case.
