(gdb) PASS: gdb.python/py-rbreak.exp: nosharedlibrary py sl = gdb.rbreak("^[^_]",minsyms=False)^M Breakpoint 2 at 0x4004ac: file ../sysdeps/aarch64/crti.S, line 63.^M ... (gdb) py print(len(sl))^M 12^M (gdb) FAIL: gdb.python/py-rbreak.exp: check number of returned breakpoints is 11 ... The FAIL is due to: - the glibc object crti.o containing debug information for function call_weak_fn, and - the test-case not expecting this. The debug information is there due to compiling glibc using a binutils which contains commit 591cc9fbbfd ("gas/Dwarf: record functions"). I've run into a similar issue before, see commit 3fbbcf473a5 ("[gdb/testsuite] Fix regexp in py-rbreak.exp"). The fix I applied there was to use a regexp "^[^_]" to filter out __libc_csu_fini and __libc_csu_init, but that doesn't work for call_weak_fn. Fix this by: - reverting the regexp to "", and - rewriting the check to require at least 11 functions, rather than a precise match. Tested on x86_64-linux.

Fixed.
