Comment (by zabrocki):
I get the same sort of problem with the following test.c program. This
seems to show that the problem is with the 'freeall' and not with the fact
that I reuse the `a` and `b` variables. `ANFANG` is making a bunch of
calls to `callocobject` for variables `a` through `h` and `ENDE` is doing
a bunch of `freeall` calls for the same variables.
{{{
#include "def.h"
#include "macro.h"
ANFANG
scan(POW_SYM,a);
t_POWSYM_SCHUR(a, b);
freeall(a);
freeall(b);
scan(POW_SYM,c);
t_POWSYM_SCHUR(c, d);
println(d);
a = callocobject();
b = callocobject();
ENDE
}}}
