Type Pattern return variable segfault

The following program OOOPses:

use Array: all;

double[m,2] Graham (double[n,2] P)
{
    return P;
}

int main () {
    P = tod (reshape ([10,2], iota(20)));
    StdIO::print ( Graham(P) );
    return 0;
}

when trying to compile with

sac2c -V
sac2c 1.3.3-MijasCosta-1121-g254711
build-type: RELEASE
built-by: "sbs" at 2023-12-04T16:12:57

using -check c.

If you replace the m in the return pattern, live is good again....
