| 00:10.36 | MonMotha | richratt: works better if you just ask a pointed question |
| 00:10.56 | MonMotha | there are several ARM people in here (and #edev), but each person tends to have a more specific area of interest/expertise |
| 00:20.49 | richratt | oh sure, well here is my situation... I am trying to debug a large embedded application, and I am receiving segmentation faults. |
| 00:22.16 | richratt | I am running the angstrom distro of openembedded linux on a ARM9 core. I also enabled user_debug in the kernel so I can get some diagnostic info about the crash. |
| 00:22.53 | richratt | In the register dump when the segmentation fault occurs, I am seeing that register R10 always points to the same address. |
| 00:24.18 | richratt | From what I understand, this is the PIC register... If I cat /proc/PID/smaps, I the address in the PIC register map to the pthreads shared library |
| 00:27.04 | richratt | Can I assume that the last shared library from which code executed before the crash was libpthread? (to clarify I do not believe that it is correct to assume I was calling something from the library when the crash occurs) |
| 00:28.03 | richratt | Let me apologize now if I am breaking any IRC-etiqute, it has been 12 years since I have been on! |

| 16:54.06 | svolpe | I'm struggling with a SEGFAULT in my application. I was hoping to track it down by backtracing the coredump however that does not seem to work and I believe that is because if the issue described here: http://gcc.gnu.org/ml/gcc/2008-11/msg00314.html Is there a better way (other than code reviewing) to track down a SEGFAULT? |
| 16:55.02 | svolpe | or can I somehow just recompile my app and glibc with -O0 as detailed in my first link? Would I need to just recompile my app or would it also require recompiling glibc? |
| 16:55.30 | svolpe | I should mention I'm developing on an ARM platform. |
