Between there appeared two new testsuite failures on Tru64 UNIX V5.1B:
FAIL: 25_algorithms/fill/4.cc (test for excess errors)
WARNING: 25_algorithms/fill/4.cc compilation failed to produce executable
Excess errors:

Confirmed with cross to armv5tel-unknown-linux-gnueabi. 4.3/4.4/4.5/4.6 all
generate the signal-unsafe epilogue.

FYI, the same failure happens on x86_64-pc-linux-gnu, but is silent for some
reason:
Leaked composite object at 0x2b5d6f749ef0

Possible fix (minimal testing)
Removing cp_as entirely seems to work. I'll have to test this some more.

Could you please provide some more details, please: what system are you running
on, what version of libelf is in use?
And please provide config.log and configure output from the toplevel and from
the gcc subdirectory,

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

Yeah, another aspect of the same issue as 44048.

(In reply to comment #19)
As indeed it does in the other case as well, which now makes me suspect that
the alpha FAIL is probably a false negative. The test code is rather old,
declares main as an implict int

GC testsuite fixes
Patch that declares int main and adds return 0; to the tests.

Hm, I'm not able to run thread_test.c and thread_leak_test.c tests using make
-k check, so otherwise deadly trivial patch can't be fully tested.

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.

The patch I posted isn't correct. It causes a regression in
gfortran.dg/cray_pointers_2.f90.
