--- Comment #5 from dmalcolm at gcc dot gnu.org --- Note: with the fix, the testcase (with an unset PATH) emits these error messages for me: libgccjit.so: error trying to exec 'x86_64-unknown-linux-gnu-gcc-5.0.0': execvp: No such file or directory libgccjit.so: error: error invoking gcc driver: exit_status: 65280 err: 0 libgccjit.so: error: whilst attempting to run a driver named: x86_64-unknown-linux-gnu-gcc-5.0.0 libgccjit.so: error: PATH was: (null) which hopefully should make it clearer that it's a PATH issue.
