gcc forgets to decrease esp after function call

[Vladimir Simonov]

Hi again,

Ok, thank you.
I'll try to prepare minimal testcase. It is not so easy
because the problem apears while handling complex
templated code.

But I need advices about workarround the problem.
Say,
How can I force gcc to use ebp instead of
esp to address local variables?

How can I force gcc to use "leave"(ebp) on function return
instead of "add XXX, esp"?

If above is possible incorrect esp hanling may
be easy workarrounded.

Thank you in advance
Vladimir Simonov
