It turns out that it is a compiler bug, or at least it is as far as we
can tell: the code works fine with -O0 but bombs with -O1.  See
https://sourceforge.net/p/asymptote/bugs/205/ for the full discussion.
I guess I should report this upstream - I guess against g++?  But
finding a minimal example will be hard.

Anyway, a workaround has been applied, and the code now appears to
compile fine under MIPS, so please do upgrade to version 2.37.  This,
incidentally, includes the elisp documentation bug patch, so that will
no longer be needed in the Debian package, and nor will the recently
applied patch from the git repo.

Best wishes,
