out of memory on dos programs

[Eric Noack]

i get a "Program too big" error on all programs compiled
with the "PowerBASIC" compiler pbc.exe 3.00c

and similar out of memory errors on other dos programs, when running them under wine

to my pleasure the pbc compiler itself runs fine under wine

here is an example:

http://gemia.de/test/test.bas

a hello world BASIC source

http://gemia.de/test/test.exe

the binary compiled with pbc 3.00c under wine

http://gemia.de/test/pbc.exe

same compiler

on every program compiled with a PowerBASIC compiler i get

"Program too big"
when running it under wine.
this string is given out by the executable when failing to allocate some memory

i tryed to disassemble the compiled program to check what type of memory allocation
should have taken place, but my dos disassembler (sourcer) failed under wine
with an out of memory error, too.

now is this a bug in wine, not handling some ms-dos memory allocation requests,
or did i just miss some configuration option to tell wine to give dos programs
more memory to allocate?

i hope this is not OT too much

I found the string "Program too big" in test.exe at position 0000:2203 hex
I guess its just given out after failing to allocate some memory ;)
as i said my disassembler doesnt work doe to some similar error
