I need to get a backtrace from a core dump file. I followed the |
| 2 |
instructions here: |

http://www.gentoo.org/proj/en/qa/backtraces.xml |
| 5 |
|
| 6 |
I added -g to CFLAGS and splitdebug to FEATURES and built the |
| 7 |
application with those new setting (that would be media-sound/lmms in |
| 8 |
this case.) I then did "ulimit -c unlimited" and started the |
| 9 |
application from that shell. I reproduced the crash and a core file was |
| 10 |
successfully produced. But, when trying to get a backtrace, I get: |
| 11 |
|
| 12 |
-------- |
| 13 |
gdb --core core --batch --quiet -ex "thread apply all bt full" -ex "quit" |

Core was generated by `./lmms'. |
| 18 |
Program terminated with signal 11, Segmentation fault. |

Then I re-emerged the application, canceled the emerge and did a manual |
| 39 |
"make" in /var/tmp/portage so I get the unstripped lmms executable. |

However, same thing as above happens. What am I missing? |
