1. I think I found what is the problem. Symbol `breakpoint_target' is defined static, so it requires debuginfo to work just after binary load in gdb. Otherwise, there is error which is unhandled by gdb smoke tester: 4.19.114-xenomai-alt1.cip24.12:~# /usr/lib/xenomai/smokey --run random_alloc_rounds=64 pattern_check_rounds=64 --run=gdb --trace=99 --verbose=99 ...

FAILURE run_gdb:287: checking expression "primary_mode", expected "$", found "N" As you can see it does not find `breakpoint_target' on `b breakpoint_target'. If debuiginfo is installed test will pass. I recommend removing `static' from `breakpoint_target' definition, so that symbol is exported without need of debuginfo. 2. There is additional problem with gdb test, though. If I have in my `.gdbinit' value of `prompt' redefined - gdb test fails to recognize the prompt. I recommend adding `-nx' option to gdb arguments so that `.gdbinit' is not read by default. gdb --help: --nh Do not read ~/.gdbinit. --nx Do not read any .gdbinit files in any directory. I believe these changes will make xeno-test more robust. 3. Also, note that `-k' switch is not worked.
