Comment (by jakobkroeker):
Tracked down to the shadowing bug ( see [http://www.singular.uni-
kl.de/forum/viewtopic.php?f=10&t=2482&sid=64e9f0044ed3cf5020d494a45172f3dc
Singular forum discussion]):
in cases we use {{{p}}} as parameter name minpoly gets lost in
primdec.lib::algedeco()
in {{{(execute(mp) := execute("poly p = p^2-p-1"))}}} statement.
The strange thing about this is that while calling Singular from sage
its losing {{{'p^2-p'}}} part , but when using standalone Singular, it is
keeping {{{'p^2'}}} and losing {{{'-p'}}}.
Strange.
