Usage of {{{Kstd1_mu}}} was introduced by my patch at #1396. The aim of
that patch was to make ''all'' Singular options available to libsingular.
Two of Singular's options involve an int parameter: {{{degBound}}} and
{{{multBound}}}. I used the former a lot, and it is kind of relieving that
it doesn't cause a problem here. The latter, however, was new to me until
two weeks ago.
So, personally, I'd say that your suggestion could be a short term
solution. But still, I'd like to see all Singular options available in
libsingular.
I'd prefer to first test whether wjp's solution works.
@wjp and @malb:
option.pyx links against certain files of Singular, located in
{{{SAGE_LOCAL}}}, if I'm not mistaken. Will installing the new spkg
automatically put these files in place? Or do you say that the spkg
actually fixes the problem already?
One general question: Is t2 really so slow, or am I getting a wrong
impression? After touching option.pyx, it took about an hour to do {{{sage
-br}}}.
Cheers, Simon
