Hi, this is fixed in GCC 7, and there is a patch for GCC 5 and 6

Hi, i finally finish testing this, is a GCC bug, octave can't compile if GCC have debug flag enabled.

Thx.

Hi!

Seems is a GCC bug, i try with all patches disabled and failed, but if i disable all USE i can, it works, at least pass all other part where fails, so now i need check what USE cause this and report it.

Thx for your help.

Hi, i'm compiling other version of GCC to test it, with any patch, is possible you say me with what options your GCC was compiled?

My octave version is from hg.

Thx.

It looks to me like you want to either report this to GCC or inspect the way that you are building GCC, maybe tweak your USE flags or something.

Many of us are continually building Octave with GCC 5, 6, and 7 with no problems, there have been no bugs observed in Octave. The main thing different here is your system and your copy of GCC.

Hi all, i don't know if this is a GCC problem or a octave problem, actually with the octave dev version i can't compile it, i get the same errors for all gcc versions i test:

I use gentoo 64, and i try compile with 5.4, 5.4-dev and 6.4 versions of GCC.

I try differents configurations for the installation but sadly the same result.

Thx.
