-r999 ebuilds aren't from the toolchain team
(In reply to Michael Jones from comment #0) > checking for the correct version of mpc.h... yes > checking for the correct version of the gmp/mpfr/mpc libraries... yes > qemu: uncaught target signal 11 (Segmentation fault) - core dumped > /var/tmp/portage/sys-devel/gcc-4.9.3-r999/temp/environment: line 4502: 29739 > Segmentation fault CONFIG_SHELL="/bin/bash" bash "${S}"/configure > "${confgcc[@]}" This looks like a bug in qemu. I'm going to be testing the new patchset introduced in response to bug #448590 on native hardware.
Entirely possible that this is a QEMU bug. For reference, I was using the recently stabilized qemu-2.5. If you think it would help, I can try other versions.
Yes, it would be interesting to see if the segfault also occurs with the previous qemu version. Does it also occur with gcc-4.9.3-r99 or with the gcc from the main tree (or by running configure from the vanilla gcc tarball)?

I'm a bit strapped for time today, so I'll have to do older qemu versions later. Perhaps on Monday, give or take.
Would there be any reason to suspect that other parts of this environment are borked? The whole system was done inside of qemu, but due to musl being under development, I've always had trouble getting things to compile (as evidenced by my bug history). Perhaps I need to start this environment from scratch?
Thanks for testing! It is likely a bug in the qemu userspace emulation. Testing another version of qemu would be useful for finding out whether it is a regression. It would be good to know what is exactly segfaulting. Take the gcc tarball and run 'sh -v ./configure' in it. This will be very verbose, but the tail should tell us what has segfaulted (assuming that there still is a segfault.)
Created attachment 424388 [details] gcc build log -- qemu-2.4
Looks like qemu 2.4 is at least able to do the configure.
It might have succeeded with MAKEOPTS=-j1. Anyway, it would be interesting to see what exactly is segfaulting. That should be easier to find out for qemu-2.5 since the segfault occurs early in the configure process when using it. Could you try running 'sh -v ./configure' and post the last few lines?

Sorry for the spam. The character limit can, sometimes, be a little restrictive :-). Hopefully that's enough information. This is with Qemu 2.5, btw.
Thanks. The log doesn't say much (my bad). The interesting output should be in config.log. Please post that (as an attachment).

Attached, as requested.
I'd also be happy to provide SSH access to the machine I'm using to do this. Essentially, the only usage this server sees is compiling various flavors of gentoo for arm boards like the raspberry pi, beaglebone, etc. I use systemd-nspawn to actually enter the specific build environments for each board, but I don't run nspawn in such a way that it sets up ip addresses and stuff for each machine. I just use a single terminal session for it. Either way, if you're interested in SSH access, let me know
It seems like that the shell itself it segfaulting. Could you also attach the output from "sh -x configure" starting from the line "+ stage1_languages=,c,"? To trim the output further, change line 2112 in configure from "' 0" to "' 99". SSH access would indeed be very useful. I might contact you before giving even more obscure instructions.

I created a clone of the environment I'm using for this for you. You can get in touch with me for ssh access whenever you want.
I had to drop all keywords on gcc-4.9.3-r999 because its breaking the stages. where did the patches for -r999 come from?
https://github.com/GregorR/musl-gcc-patches/tree/gcc-4.9.3
@blueness: What kind of problem has the -r999 ebuild caused for the stages? (Part of the patches is necessary for go-bootstrap.) The bug experienced by the OP is likely bug 518598 (determined using ssh access).

Try to build a stage3 for i686 and you get issues with __stack_chk_fail_local. I didn't trace it down. Perhaps this can be fixed in conjunction with providing this symbol as alpine does. I didn't have time to nail it.
Do we still need this?
We're long away from gcc 4.9.3 and current GCCs are fine.
