Description:

uShare every now and then segfaults when accessing media files in my server from my boxeebox client. I've tried with one single broadcasted directory and also with "only" 4 subdirs with slightly less files. I've seen the error in all the latest ushare packages since I own that boxeebox device. Haven't used the server before. Sergej, are you sure building this pkg against glibc from core?

[root@server64 andyrtr]# ps aux | grep ushare
ushare 8782 0.3 0.6 250404 24180 ? Ssl 22:57 0:01 /usr/bin/ushare -D -x

Additional info:
ushare 1.1a-13
glibc 2.13-5

dmesg says:

ushare[1510]: segfault at 2c0039a0 ip 00007fe53b57c77c sp 00007fe533a742e8 error 4 in libc-2.13.so[7fe53b500000+154000]

Any idea how to provide further information?

It works here it seems, is your config ok? paste it.

It segfaults not right at the start. It works for for some time and at some point when changing a directory or accessing files it segfaults.
   ushare.conf (1.5 KiB)

Unassigning me as it is unlikely to be a glibc issue.

Can this bug be reproduced now? I can successfully listen mp3 for about hour.
Comment by Andreas Radke (AndyRTR) - Saturday, 03 September 2011, 13:50 GMT
I can see the bug every now and then accessing video and photo files. mp3 seems to work fine here. btw: I'm using it via (D-Link)BoxeeBox.

Feel free to close this one for now. Once I find a way to reproduce it I will try to get a backtrace with a debug build.

Contacted upstream.

The email to upstream bounced.

The only point of contact for ushare that is mentioned on the homepage is ushare@geexbox.org. Ref: http://ushare.geexbox.org/#Feedback

There is no mention of a bug tracker, project pages, irc channels, mailing lists or any other way to contact anyone.

Googled the author and e-mailed ben@geexbox.org.

Got no reply from Ben so far. Please consider moving this package to unsupported.

I applied patch. Not sure if it helps - please check it. If it is not solution, probably I'll move it to aur.

On my system (64bit), I use this patch for a month. No more segfaults :)
Problem is solved by the patch: mixing 32-bit and 64 bit pointers. This happens if the compiler does not find a definition of the standard functions in header files. On a 64 bit system automatically uses the 64 bit function, even though the program is 32 bit.
