Stack Bug in ZXB 1.2.5-r1489 ?

[apenao]

I've downloaded the new version (1.2.5-r1489f) and tried to compile my last crap game. It compiled OK with version 1.2.5-r1489 and no optimization.

Now, with no optimization I get this message (and it compiles OK):

Code:

> Executing: C:\Archivos de programa\ConTEXT\ConExec.exe -i "C:\Archivos de programa\Boriel Tm\ZX Basic Compiler\zxb.exe" -T -B -a  -S 28000 clash3.bas

memcopy.bas:29: warning: SUB 'memcopy' declared as FASTCALL with 3 parameters
> Execution finished.

With optimization -O 2, or -O 3 I get this message (and it doesn't compile):

Code:

> Executing: C:\Archivos de programa\ConTEXT\ConExec.exe -i "C:\Archivos de programa\Boriel Tm\ZX Basic Compiler\zxb.exe" -T -B -a  -O 2 -S 28000 clash3.bas

It's probably my code (I'm so proud of its crapyness...) but maybe the last lines of the optimization message tells you something. I don't want to make you search within a long, untidy, unsorted and crap piece of code, so if you can point me to what should I look for, I'll do. Or if you think it's my code's fault I'll let it as is (it compiles without optimization and that more than enough for me).

Anyway, if you still want to see my code, I'll send you the .bas file, the attachments and also the .tzx file so you can play and delight yourself (or not).
