What do I have to do to run an assembler procedure from C?
I compile assembler code to borland .obj file, then convert
it into .o, link it with main program's .o file and it works,
but _sometimes_ there are some bugs. For example a black
horizontal line appeares on the screen (in a triangle draw
procedure), but _only_ sometimes (ie I run the program - the
bug is visible, I run the program for the second time - there's
no bug)

Maybe I forget to allocate some memory for stack or something...

My program does the following:

1. in c:
 data=(char *)malloc(100);

2. in assembler:
 selector - _my_ds()
 offset   - data
 it uses the allocated memory (read & write)

...and as I said it works, but sometimes doesn't? Why? Please help me.

PS. Sorry for my english.
