[fpc-devel] Bug 18702

[Joost van der Sluis]

Hi all,

Seems like it that bug 18702 has nothing to do with my changes to the
stack-balancing code, and that nested function proc's never functioned
well on Windows.

The problem is that pop_parasize() is used to pop the stack-frame
pointer form the stack. But on 32-bit Windows, pop_parasize() has some
code to ensure that the funcret pointer is removed from the stack by the
caller. This is not applicable to the situation where only the
stack-frame pointer has to be popped from the stack.

A possible solution is attached, but I didn't commit it yet because I'm
nut sure if it is 'allowed' to use a 'target_info.system =
system_i386_win32' condition in ncgcal.pas. Other solutions could be to
add a parameter to pop_parasize or to add something like
pop_funcret_parasize().

Thoughts?

Joost.
