I am using gdb 7.2-14.fc14 to work on a large multi-threaded application, in C, x86-64. (AMD Phenom II X6 1090T) I have .gdbinit, per the book: set target async 1 set pagination off set non-stop on When I step using 's' or 'n', as it leaves some subroutines I keep getting SIGSEGV, such as: Program received signal SIGSEGV, Segmentation fault. signal_set (signo=Cannot access memory at address 0xffffffffffffff5c) at ... When I 'disass' the current instruction is a leaveq. Examining the registers I observe that rbp is zero, which is clearly nonsense. I found one instance which was repeatable, which happened to be before any threads were started: if I 'ni' through a particular function, it gets to the leaveq, and gets stuck there. Each time I do ni, the rsp and the rbp are updated by the repeated leaveq, until it goes bang. So... this doesn't appear to be to do with multiple threads... ... here is a trivial test: <<--test.c----------------------------------------------- #include <stdio.h> #include <stdlib.h> static void target(const char* message) { printf("%s ...BANG!\n", message) ; } int main(int argc, char* argv[]) { target("Light the blue touch paper") ; return 0 ; } ------------------------------------------------------->> Compiled by gcc 4.5.1 "-g -O0". If I do "gdb test", stepping by "n": <<------------------------------------------------------- (gdb) show non-stop Controlling the inferior in non-stop mode is on.

So this is something to do with debugging multi-threaded ! I note also that if I change the target to: static int target(const char* message) { printf("%s ...BANG!\n", message) ; return 0 ; } the problem goes away... so one extra instruction between the callq and the leaveq makes a difference: 0x00000000004004dc <+24>: mov %rax,%rdi 0x00000000004004df <+27>: mov $0x0,%eax 0x00000000004004e4 <+32>: callq 0x4003b8 <printf@plt> 0x00000000004004e9 <+37>: mov $0x0,%eax 0x00000000004004ee <+42>: leaveq 0x00000000004004ef <+43>: retq
Using step or next on return in non-stop mode crashed the program. *** This bug has been marked as a duplicate of bug 15520 ***

In non-stop mode, when a breakpoint is removed, it is moved to the "moribund locations" list. This is because other threads that are running may have tripped on that breakpoint as well, and we haven't heard about it. When a trap is reported, we check if perhaps it was such a deleted breakpoint that caused the trap. If so, we also need to adjust the PC (decr_pc_after_break). Now, say that, on x86: - a breakpoint was placed at an address where we have an instruction of the same length as decr_pc_after_break on this arch (1 on x86). - the breakpoint is removed, and thus put on the moribund locations list. - the thread is single-stepped. As there's no breakpoint inserted at PC anymore, the single-step actually executes the 1-byte instruction normally. GDB should _not_ adjust the PC for the resulting SIGTRAP. But, adjust_pc_after_break confuses the step SIGTRAP reported for this single-step as being a SIGTRAP for the moribund location of the breakpoint that used to be at the previous PC, and so infrun applies the decr_pc_after_break adjustment incorrectly. The confusion comes from the special case mentioned in the comment: static void adjust_pc_after_break (struct execution_control_state *ecs) { ... As a special case, we could have hardware single-stepped a software breakpoint. In this case (prev_pc == breakpoint_pc), we also need to back up to the breakpoint address. */ if (thread_has_single_step_breakpoints_set (ecs->event_thread) || !ptid_equal (ecs->ptid, inferior_ptid) || !currently_stepping (ecs->event_thread) || (ecs->event_thread->stepped_breakpoint && ecs->event_thread->prev_pc == breakpoint_pc)) regcache_write_pc (regcache, breakpoint_pc); The condition that incorrectly triggers is the "ecs->event_thread->prev_pc == breakpoint_pc" one. Afterwards, the next resume resume re-executes an instruction that had already executed, which if you're lucky, results in the inferior crashing. If you're unlucky, you'll get silent bad behavior... The fix is to remember that we stepped a breakpoint. Turns out the only case we step a breakpoint instruction today isn't covered by the testsuite. It's the case of a 'handle nostop" signal arriving while a step is in progress _and_ we have a software watchpoint, which forces always single-stepping. This commit extends sigstep.exp to cover that, and adds a new test for the adjust_pc_after_break issue.
