            Bug ID: 105561
           Summary: Nondeterministic ICE on creation of
                    bits/stdc++.h.gch/O2g.gch and
                    bits/extc++.h.gch/O2g.gch
           Product: gcc
           Version: 12.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: swilde@sha-bang.de
  Target Milestone: ---

I'm experiencing a strange, not deterministic ISE on creation of
bits/extc++.h.gch/O2g.gch and bits/stdc++.h.gch/O2g.gch during building
of gcc 12.1 on i386 NetBSD 9.2.

I know the following sounds like an hardware problem, but it certainly
is not, as it can be observed in the exactly same way on to totally
different hardwares:

1. A native system running NetBSD 9.2 (i386):
   Intel(R) Atom(TM) CPU N270   @ 1.60GHz
   2 GiB RAM

2. A virtual system running NetBSD 9.2 (i386):
   VirtualBox guest with
   11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
   16 GiB RAM (for the guest)

The symptoms are identical on both.

It happens during bootstraps well as during non boostrap compilation
with an already compiled gcc 12.1.

My configuration Options are:

../gcc-12.1.0/configure \
  --with-bugurl=https://github.com/jashandeep-sohi/libgccjit-pkg/issues \
  --enable-shared --enable-host-shared --enable-checking=release \
  --enable-languages=jit --disable-multilib --disable-libssp \
  --disable-lto --disable-libquadmath --disable-liboffloadmic \
  --disable-libada --disable-libsanitizer \
  --disable-libquadmath-support --disable-libgomp --disable-libvtv \
  --disable-libsanitizer --with-gmp=/usr/local --with-mpc=/usr/local \
  --with-mpfr=/usr/local 

Here is what happens (I'll choose bits/extc++.h.gch/O2g.gch as an
example, the exact same thing happens for bits/stdc++.h.gch/O2g.gch,
too):

The compilation fails like this:

Then I try to compile the file by hand, which usually fails, too some
times, but eventually succeeds:

------------------------------------------------------------------------

After doing this exercise for the two header files the compilation can
be restarted using gmake and finishes as expected...

The problem only ever arises with this two files, but for those I
experienced it every time I build gcc 12.1 on NetBSD 9.2.

I'm fully aware, that this looks like an hardware problem, but it
really happens independently of the hardware used.
