Yes, that looks like the right thing to do.
My plan is to take your Singular-malloc spkg and turn it into a "proper"
spkg, in the sense that the changes that you did to the source code will
become patches that are ''optionally'' applied (say, if one does `export
SAGE_SINGULA_MALLOC=yes`).
The backported fix will of course be an unconditional patch.

within your reach to investigate? I'm not really comfortable tracing
through templated C++.
Neither am I. But at least (in contrast to me!) you are comfortable to
work with valgrind! Perhaps you could open a ticket to make your `.supp`
file available to people? After all, there is a totally outdated valgrind
spkg...
