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.
