[Bug target/44099] New: ICE in g++.dg/debug/nullptr01.C test on Solaris 2/SPARC

[ro at gcc dot gnu dot org]

The new g++.dg/debug/nullptr01.C test currently fails on Solaris 10/11 SPARC:

FAIL: g++.dg/debug/nullptr01.C -gdwarf-2 -g1 (internal compiler error)
FAIL: g++.dg/debug/nullptr01.C -gdwarf-2 -g1 (test for excess errors)
ERROR: g++.dg/debug/nullptr01.C: error executing dg-final: couldn't open "nullp
tr01.s": no such file or directory

g++.log reveals:

/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/debug/nullptr01.C: In function
'std::nullptr_t g(T) [with T = A<std::nullptr_t>, std::nullptr_t =
std::nullptr_t]':

Isn't that again a C++ tree code that leaks into the back-end?

Yeah, another aspect of the same issue as 44048.

*** This bug has been marked as a duplicate of 44048 ***

I get the same errors with nullptr01.C on sparc64-unknown-linux-gnu. My build
has c++ as an enabled language, and most other c++ and libstdc++ tests work, so
I don't think this is a dupe of PR44048.

I marked it as a dupe because it has the same cause, though different specific
effects.
