--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Or maybe print something like: BEGIN QUOTE /home/jwakely/src/gcc/gcc/gcc/selftest.c:305: test_locate_file: FAIL: unable to open file: ./example.txt A gcc selftest has failed. Investigation of the source location above may reveal the problem. Alternatively, you can disable selftests by doing [add method here], although the selftest failure may be a symptom of a deeper problem with your configuration. The backtrace leading to the failure was: cc1: internal compiler error: in fail_formatted, at selftest.c:62 0x13dcde6 selftest::fail_formatted(selftest::location const&, char const*, ...) /home/jwakely/src/gcc/gcc/gcc/selftest.c:62 0x13dd157 selftest::read_file(selftest::location const&, char const*) /home/jwakely/src/gcc/gcc/gcc/selftest.c:164 0x13dd48f test_locate_file /home/jwakely/src/gcc/gcc/gcc/selftest.c:305 0x13dd48f selftest::selftest_c_tests() /home/jwakely/src/gcc/gcc/gcc/selftest.c:320 0x138a47b selftest::run_tests() /home/jwakely/src/gcc/gcc/gcc/selftest-run-tests.c:55 0xbe37e2 toplev::run_self_tests() /home/jwakely/src/gcc/gcc/gcc/toplev.c:2075 If you think this is a bug in gcc itself, please submit a full bug report. Please include the complete backtrace with any bug report, and details of your configuration, and the command line. See <https://gcc.gnu.org/bugs/> for instructions. END QUOTE
