that is clear the thumb bit of the address before passing it to `set_hw_breakpoint` fixes a bug (\*) where the microcontroller will pause at the *second* instruction of `HardFaultTrampoline` rather than the first Observed with these values: - `vector_table.hard_fault` = 0x7dc - PC read at breakpoint (in `backtrace`) = 0x7de ``` armasm 000007dc <HardFaultTrampoline>: 7dc: 4670 mov r0, lr 7de: 2104 movs r1, #4 ``` (\*) observed bug behavior: `<exception entry>` was not printed and exit code was 0 (instead of SIGABRT)
