--- Comment #1 from Sam James <sjames at gcc dot gnu.org> --- glibc's WAIT_FOR_DEBUGGER support for tests seems broken, as it drops me into a waiting process with: ``` /var/tmp/portage/sys-libs/glibc-2.38-r10/work/build-arm-armv7a-unknown-linux-gnueabihf-nptl/posix/tst-getopt-cancel.gdb:6: Error in sourced command file: 'wait_for_debugger' has unknown type; cast it to its declared type ``` Can't manually set wait_for_debugger either. Whatever. Trying manually, we get (without very good debugging symbols yet): ``` Thread 2.1 "ld-linux-armhf." received signal SIGSEGV, Segmentation fault.
