Bug#813784: g++ fails to compile asymptote 2.35-4 correctly on MIPS with -O1 or higher optimisation
Package: g++-5
Version: 5.3.1-7
Severity: normal
In an attempt to track down the reason for bug#808821, I had an
extended discussion with the asymptote upstream, see
https://sourceforge.net/p/asymptote/bugs/205/
I came to the conclusion (using minkus) that the compilation works
with -O0 optimisation but not with -O1 optimisation, for some strange
reason that we couldn't fathom. (I controlled the optimisation by
modifying the Makefile CFLAGS setting after running configure.)
I don't know how to construct a minimal case or how to further
investigate this beyond what I have already described in that bug
report, unfortunately. It pretty much builds fine on all of the other
architectures; at least none of them exhibit the same error.
