Stack misaligned

[mineiro]

Hello sir John;
How are you? I hope fine.
Symptom: Stack misaligned using invoke in procedures "buffer_insert_text" and "control_g".
Test: If the first two invokes in the first two procedures are commented out then the stack in later functions aligns to multiples of 16 and works ok.
This is why I included them in this test case, same functions in different procedures are conflicting.
Before refining this test case, I noticed that the listing while assembling was generating correct opcodes but the resulting object file was stack misaligned.
In this test case the listing (opcodes) is a bit ghost. Could you take a look, please? Thank you in advance.

I'll have a look at this. Could you possibly add this to Github issues page ? - if not I can create an issue for it. Thanks!

Unfortunately I don't have a github account, sorry to say that I can't post an issue.
Thanks.

No prob!
