Description wilhelm hagg 2009-02-21 23:20:27 UTC

When vdr is shutting down and unloads the plugin it crashes whith:

segfault at b61649c1 ip b7cababb sp b06f3b84 error 4 in 
libgcc_s.so.1[b7ca6000+a000]

When i disable the lcdproc plugin i get no crash, so i guess lcdproc causes the problem.

Also if i go back to a recent lcdproc version (0.0.10.3) i get no crash.

The crash is critical as i assume that the crash is the reason why vdr deletes my timers. 

VDR crashes nearly every time when it is stopped (90 %). The timers are deleted very rarely, maybe at one out of 20 crashes.

Reproducible: Sometimes

Steps to Reproduce:
1. /etc/init.d/vdr stop

I am added vdr-lcdproc-0.0.10.6 to portage

Please test, is it fixed in this version.

Comment 2 Matthias Schwarzott gentoo-dev

If not fixed, you should create a backtrace by running

gdb -p $(pidof vdr)
cont

and then stopping vdr as usual by
/etc/init.d/vdr stop

as soon as vdr crashes, gdb will give you a prompt, where you get a nice backtrace with "thread apply all bt full".

Comment 3 wilhelm hagg 2009-02-27 23:16:50 UTC

Yes, it's still there with vdr-lcdproc-0.0.10.6

Here is a backtrace. Is this fine or do you need one with symbols?

Does this still happen with 0.0.10.9?

Comment 5 Joerg Bornkessel 2019-11-13 17:10:54 UTC

could we set this bug to invalid or wantfix?
as no feedback after 10 years
