Comment (by zabrocki):
Mike H. posted a test.c program to try out in Symmetrica.
{{{
#include "def.h"
#include "macro.h"
ANFANG
scan(POW_SYM,a);
t_POWSYM_SCHUR(a, b);
println(b);
ENDE
}}}
Run this program with input "36" followed by thirty-six "1"'s, followed by
"1" (to indicate an integer coefficient), followed by "1" (to indicate
that the coefficient is 1) "n" and the output says again
`5.061293.630159.021056 111122334567`. This means that the error is
within Symmetrica.
