Hi, I apologize if this is not the right list for this kind of questions,please point me to a better one that is the case.
Now,what I want to do is to generate stack traces from a running program. That is no problem with gcc's __builtin_frame_address function. But I'm having problem getting that to work from a signal handler,in this case for SIGSEGV. Output from test program: bash-2.05b$ ./dump looking up address 0x80488c4 in frame 0xbfbff6a8 looking up address 0xbfbfffac in frame 0xbfbff870 looking up address 0x8048621 in frame 0xbfbff8bc ext Stack: handle_SEGV_ext 0xbfbfffac _start Abort trap (core dumped) address is the return address of previous function called and frame is the stack frame. I generate the SEGV from main. But as you can see I can't get the address of the function that generated the signal/exception/trap. I tried looking into /sys/i386/i386/trap.c to look for hints on how to get the adress where the fault happened,but I was kind of lost :) So my question is,is it possible to find out the address where a fault occured from userspace? Please reply to me directly since I'm not on the list.
