Hmmmm... bad. If I get nothing tomorrow morning, I'll decide it's stuck

It got stuck.

But I noticed it doesn't get stuck when I build upstream's sources
directly (ie: without the debian flags). I'm now bissecting to find out
exactly what triggers the problem.

The transition is on hold until the matter is settled.


There's a good chance it's a compiler bug... I reported:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=798149

In the mean time, what should I do? There's the option of waiting, or I
could disable the hardening-flags and override the lintian warnings and
still try to push the transition...

Hi,

I think it's unlikely that the Debian gcc maintainers will debug this,
because it is still totally unclear what the problem is. It's more
likely that the flint maintainers would be interested to debug this
further. Maybe they even know about this and can tell you which
optimization may cause this, then one could disable only that one. It
would be also ok to use the optimization level that flint uses by
default if that solves the problem.

Best,
Tobias


Flint's upstream doesn't have access to an i386 box and thinks it's a compiler issue, so they're not very interested in debugging it.

The problem is the -O2 flag, and we get it from dpkg-buildflags... which is strange since I remember upstream also uses it...

I might have another idea to test!

Cheers,

Snark
