Change the line
if (type == LM_TC_BSYM)
in support.C (whichFont)
to
if (type == LM_TC_BSYM || type == LM_TC_CMEX)
BTW, with my patch, big operators are now stored using symbolinset and not
bigopinset. The bigopinset inset should probably be removed.
There is still a problem that the bigoperators don't have
displaylimits positioning of super/subscripts but it shouldn't be hard to
fix.
PS: the numargs field in the latexkeys struct is not used.
For example, in a binary operator like \leq, you don't add spaces before
and after it.
Note that spaces are added before/after < or +, which means they are not
implemented using symbolinset.
