Memory leak with PUSHMARK and PUTBACK

[Uwe Gansert]

Hi,

I'm fighting with using Perl Modules from within C programms.
While digging into that topic, I'm wondering why the following simple C
function is a memory leak:


void leak() {
dSP;
PUSHMARK(SP);
PUTBACK;
}

calling this function in an endless loop, eats up all free memory.
perl -v => "This is perl, v5.8.5 built for i586-linux-thread-multi"

Nothing ever consumes the marks, so you keep the markstack growing.
