I seriously have no idea which component is affected here, so will guess a
value.

Just put the error message here and we will decide.

Note the preprocessed source does not compile with a GCC 12 (due to aarch64
backend changes), so it might take a while to reproduce the issue and such.

works with: 

gcc-10.3.0
gcc-10.3.1_p20211126
gcc-11.3.0

does not work with: 

gcc-10.4.0

the segfault is sort of spurious, its an about 1/5 to 1/7 chance for me. Is
that something you can work with?   

and indeed these are two seperate segfaults, I got the -O1 from comment #4 now
reproduced with -O2 as well

started with pr105998 

commit 20bb976fb6a853d4f79577278ac2f01622946b61
Author: Jakub Jelinek <jakub@redhat.com>
Date: Sat, 18 Jun 2022 09:07:13 +0000

varasm: Fix up ICE in narrowing_initializer_constant_valid_p [PR105998]

The following testcase ICEs because there is NON_LVALUE_EXPR (location
wrapper) around a VAR_DECL and has TYPE_MODE V2SImode and
SCALAR_INT_TYPE_MODE on that ICEs.  Or for -m32 -march=i386 TYPE_MODE
is DImode, but SCALAR_INT_TYPE_MODE still uses the raw V2SImode and ICEs
too.

2022-06-18  Jakub Jelinek  <jakub@redhat.com>

PR middle-end/105998
* varasm.c (narrowing_initializer_constant_valid_p): Check
SCALAR_INT_MODE_P instead of INTEGRAL_MODE_P, also break on
! INTEGRAL_TYPE_P and do the same check also on op{0,1}'s type.

* c-c++-common/pr105998.c: New test.


here is how I did it: 

the first bad version is 10.4.0-RC
the last good version is 10-20220616

Its just a handfull of commits between those snapshots, so I compiled
10-20220616 and added those commits subsequentially, via local patch files. 

Its a problem though that cross-compiler doesn't confirm the ICE, and native
compile is kind if heisenbugging around. I'll ask the original author if he has
any suggestion what could happen here. 

gcc-11.3.0 is not affected, as the fix landed for gcc-11.4.0 and I haven't yet
found the time to test these snapshots.

I suspect this is a GC (garbage collection) issue.
It might be easier to reduce it using --param ggc-min-expand=1 --param
ggc-min-heapsize=1 (and then moving them both to 0 afterwards).
