I've been able to reproduce the problem on 32-bit Ubuntu 20.04 for RPi4. The problem reproduces when the following is linked:
ld-linux-armhf.so.3 -> ld-2.31.so* fostja@cptr280-arm:~/code/asm$ gdb -q hello GEF for linux ready, type `gef' to start, `gef config' to configure 75 commands loaded for GDB 9.2 using Python engine 3.8 [*] 5 commands could not be loaded, run `gef missing` to know why. Reading symbols from hello... gef➤ set debug infrun 1 gef➤ b _start Breakpoint 1 at 0x1016c: file hello.s, line 5. gef➤ start infrun: infrun_async(1) infrun: proceed (addr=0xb6fd5a80, signal=GDB_SIGNAL_0) infrun: proceed: resuming process 10100 infrun: resume (step=0, signal=GDB_SIGNAL_0), trap_expected=0, current thread [process 10100] at 0xb6fd5a80 infrun: prepare_to_wait infrun: target_wait (-1.0.0, status) = infrun: -1.0.0 [process -1], infrun: status->kind = ignore infrun: handle_inferior_event status->kind = ignore infrun: prepare_to_wait infrun: target_wait (-1.0.0, status) = infrun: -1.0.0 [process -1], infrun: status->kind = ignore infrun: handle_inferior_event status->kind = ignore infrun: prepare_to_wait When I revert to the following then things work properly: ld-linux-armhf.so.3 -> ld-2.28.so* So I have a work-around. It appears that the problem was introduced between 2.28 and 2.31. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901966 Title: Unable to stop at breakpoint in 32-bit executable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1901966/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
