Created attachment 473200 [details] gcc-build-logs.tar.bz2 After upgrading to gcc-6.3.0, I uninstalled gcc-5.4.0.

same problem here, also with 6.4.0 on hardened.

@ hardened - any idea?
Created attachment 497404 [details, diff] applay -no-pie on stage1 build This patch applay -no-pie to stage1 ldflag so we can build older gcc with pie enable gcc

This patch works for me. Is it ment to be applied on the affected gcc-5.4.0 or the active gcc-6.*?
(In reply to Attila Tóth from comment #8) > Is it ment to be applied on the affected gcc-5.4.0 or the active gcc-6.*? The patch has to be applied to gcc-5.4.0.

> -STAGE1_LDFLAGS = @stage1_ldflags@ > +STAGE1_LDFLAGS = @stage1_ldflags@ -no-pie That will work only for host gcc-6+, right? My understanding is gcc-5.4.0 calls it -nopie and we can't apply the patch unconditionally.

Created attachment 504542 [details, diff] Patch toolchain eclass with a sed to add -no-pie This patch the eclass so we don't need to update the patchset. We use a sed to add the needed the -no-pie
