Comment (by vbraun):
For the record, matrix_modn_dense_template.pxi with some extra prints:
{{{
else:
print 'word_size != sizeof(char)', word_size, <int><char*>s
um = <mod_int*><char *>s
for i in range(self._nrows):
row_self = self._matrix[i]
row_um = &um[i*self._ncols]
for j in range(self._ncols):
print i, j, row_self[j], <mod_int>row_self[j],
self._ncols, self._nrows, <int>row_um
row_um[j] = <mod_int>row_self[j]
print "crash"
}}}
yields
{{{
