[I finally provide a small source file and steps for processing it to produce the BFD_ASSERT notices.]

Any > help appreciated. :-) NOTE: Only tested in the powerpc64 context, with system clang 8 for c++ and base/binutil for ld and such. I used the simple_version_script.map from llvm60 in my environment. (Also noted in bugzilla comment #13:) The following small source code file and the few steps to build/link it produce the message: # more small_link_failure.cpp unsigned long fixed_seed_override= 0xdeadc0de; inline unsigned long get_execution_seed() { const unsigned long seed_prime = 0xff51afd7ed558ccdULL; static unsigned long seed = fixed_seed_override ? fixed_seed_override : (unsigned long)seed_prime; return seed; } unsigned long f() { return get_execution_seed(); } # c++ -c small_link_failure.cpp # rm -f small_link_failure.a # /usr/bin/ar qc small_link_failure.a small_link_failure.o # "/usr/bin/powerpc64-unknown-freebsd13.0-ld" \ "-Bshareable" \ "-o" "small_link_failure-1.0.so" \ "/usr/lib/crtbeginS.o" \ "--version-script" "/wrkdirs/usr/ports/devel/llvm60/work/.build/./lib/tools/llvm-shlib/simple_version_script.map" \ "--whole-archive" \ "small_link_failure.a" \ "--no-whole-archive" \ "-lm" # /usr/bin/powerpc64-unknown-freebsd13.0-ld \ "-Bshareable" \ "-o" "small_link_failure.so.1.0.1" \ "small_link_failure-1.0.so" The resultant output is: /usr/bin/powerpc64-unknown-freebsd13.0-ld: BFD (GNU Binutils) 2.32 assertion fail elflink.c:2935 /usr/bin/powerpc64-unknown-freebsd13.0-ld: BFD (GNU Binutils) 2.32 assertion fail elflink.c:2935 === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "[email protected]"
