#9412 closed Bug Report - Crash (Works for me)
[CRASH] Channel History and FE Control Socket - segfault on scripted "h"/back
Reported by: | Owned by: | cpinkham | |

Priority: | trivial | Milestone: | 0.25 |

Description (last modified by )
Was playing with "h" Channel History command and the Frontend Control Socket http://www.mythtv.org/wiki/Frontend_control_socket
For testing purposes, I start the FE this way: DISPLAY=:0 /usr/bin/mythfrontend --service &
This case operates reliably:
Enter LiveTV Tune 3-4 channels Use wired keyboard letter "h" to go back in channel history (I can repeat this several times, no crash)
This case segfaults...:
Enter liveTV tune 3-4 channels Use command line "nc localhost 6546 < mythcmd" -- where 'mythcmd' contains only text "key h" (no quotes in file)
After 1-2 calls from the command line (call script, wait for channel to tune, call script), the FE crashes. No errors produced in FE logs, even with -v channel,socket
[1]+ Segmentation fault DISPLAY=:0 /usr/bin/mythfrontend -v channel,socket
I'm sure I need to tell you more, do I need to take this to the bug reporting tool or am I trying to make something work in the wrong way?

If you segfaulted, you should have a core dump laying around (mythfrontend.core) in whatever was the current directory mythfrontend was already in. Please see the documentation on obtaining a traceback from it.

I've done as you asked for gdb capture during the crash. Pls let me know if I've done incorrectly, is my first such debug.

I can't get this to crash. Please reopen if this is still a problem in your test case in post-release 0.25.
