I'm reverse engineering an old DOS game that's using the DOS/4GW extender. The game includes some libraries that I already successfully reversed in a different application, so I'm pretty sure that the declaration for the function that is making trouble is correct. Nonetheless, the function in question shows the error message
// local variable allocation has failed, the output may be wrong!.
When looking at the assembly, it seems like there's a problem with the stack definition, as can be seen here:
I already tried to edit the function and make some adaptions (unfortunately I'm lacking a little bit of experience there), but to no avail. Here's a screenshot of the declarations/stack frame and the function's initial options without changes:
What could be the cause for the failed allocation and how can one fix it?
