Hello. As slightly discussed with Mark, there are tests that expect 'main' will be present in backtrace. That's not always true on x86_64 because -freorder-blocks-and-partition option is on by default. Then one can see:
[ 88s] FAIL: run-backtrace-dwarf.sh [ 88s] ============================ [ 88s] [ 88s] 0x7f1fd49800cb raise [ 88s] 0x7f1fd49694e9 abort [ 88s] 0x5627fddd0188 callme [ 88s] 0x5627fddd0192 doit [ 88s] 0x5627fddd01a3 main.cold.1 [ 88s] 0x7f1fd496afeb __libc_start_main [ 88s] 0x5627fddd04aa _start [ 88s] /home/abuild/rpmbuild/BUILD/elfutils-0.173/tests/backtrace-dwarf: dwfl_thread_getframes: no error [ 88s] 0x5627fddd01a3 main.cold.1 Thus I'm suggesting to disable the option for tests? Thoughts? Martin
