--- Comment #2 from Jakub Jelinek  ---
Can be reproduced even on x86_64-linux with
CXXFLAGS='-g -O2 -D_GNU_SOURCE -gno-as-loc-support'
cxx11-ios_failure-lt.s: Assembler messages:
cxx11-ios_failure-lt.s: Fatal error: duplicate .debug_line sections
make: *** [Makefile:766: cxx11-ios_failure.lo] Error 1

Otherwise it just creates duplicate debug info.

Created attachment 43969

gcc8-pr85442.patch

Perhaps we want to assemble with -g0, because either the .s file already
contains debug info from the compiler and then we don't want to add one from
the assembler, or the user doesn't want debug info at all.

Completely untested though.
