i386-pc-solaris2.11 32-bit xtreme-header-2_a.ii
Several of the new modules tests FAIL on Solaris/x86, Solaris/SPARC, and
FreeBSD,
e.g.
+FAIL: g++.dg/modules/xtreme-header-2_a.H -std=c++2a (internal compiler error)
+FAIL: g++.dg/modules/xtreme-header-2_a.H -std=c++2a (test for excess errors)

However, with -std=c++17 the tests PASS.
The failure can be reproduced for the first test with
$ cc1plus -fpreprocessed xtreme-header-2_a.ii -quiet -std=c++20 -fmodule-header
-o xtreme-header-2_a.s
and the attached .ii file.
