So I can confirm the issue trying to build gcc10 packages for SLE11 ppc64
(after much massaging). It works fine (past the failure point) on x86_64
with the same versioned host compiler. It works fine

Usually I'm trying to do binary search in these cases, build one tree with the
bad compiler, one with good one, cp -al one of the trees to a new dir, make a
list of the object files, start with half/half,

Swapping out those two .o files (individually and together) didn't yield a
successful build. I brought in the 8.4.0 .o files in one at a time and
eventually I got a successful build but at that

Built r152973 ../configure --disable-bootstrap --enable-languages=c,c++ ,
installed and built gcc trunk with that as system compiler and can't reproduce
it. Maybe some SUSE patches or the SUSE compiler was

It is during stage1 and I was able to recreate using the system distro
compiler, gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux). I
will bisect on the .o's now.
FWIW here is a

I will try to recreate but I got rid of the old build compiler. It was a
leftover from some work many years ago and I had forgotten I was even using it.

GCC 10 doesn't require C++11 and so in theory everything from GCC 4.1 till GCC
11 should be supported as system compiler, perhaps we need some workaround for
some known bugs somewhere (we have a couple of

Can't reproduce btw, ../configure --enable-languages=c,fortran,c++

Could you please attach preprocessed source so that I can try to look at it
quickly with a cross-compiler? Thanks.
