Segmentationfault #214

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Segmentationfault on compilation of todays source 
(r=1242280417c39780fddcf89537b0f80fcfbffa31). This is with both default gtk and 
--enable-gtk3. Earlier revision from 2012-08-19 has worked flawlessly.

Please advise how to find the error, since starting from terminal does only say 
segm. fault.

I'm on Arch linux with:
gtk3 3.4.4-1
libproxy 0.4.7-2
libunique 1.1.6-5
json-glib 0.14.2-1
gcc 4.7.1-6
autoconf 2.69-1

I do have these installed; 'gtk3' 'hicolor-icon-theme' 'geoip' 'libproxy' 
'libunique' 'json-glib' 'libnotify' 'gconf' 'desktop-file-utils' 'curl'

Am I missing something? What more info is needed to find the bug?

Stable version 1.0.2-1 compiled source from works totally fine.

Hi,

Lots of changes since the 19th :) I've added a new Transmission UI style.

I'll need a gdb backtrace, with the debugging symbols present. If you're 
compiling from source you probably want to 'gdb path/to/binary', 'run', then 
'bt full' when it crashes. See here for more info:

Thanks for the prompt reply. Followed the arch wiki and ran gdb and bt. This is 
the output, hope you can interpret it:

That particular line is where lots of members from the JSON object are copied 
into the GTK model, so it could be any one of them. 

I've put the debug statements (one member per statement) back there. If you 
update, ./configure with --enable-debug, rebuild, and collect the backtrace 
again I hope this will be more specific.

Thanks.

With --enable-debug as you said.

Should be fixed now. I think it was a mismatch between an unsigned int and a 
64bit signed int in one of those new fields I added.

Unfortunately these bugs don't cause crashes for me. Seems to cause crashes on 
32bit more, and some other distros (maybe depends on compile flags).
