Hi List & Robert, I only found out one important thing:
viking only crashes if "Autodownload Maps" is enabled while using real time gps. If I do not select "autodownload maps" real time gps tracking works just fine. > Hmm I still can now sometimes get it to fail but only on an EeePC machine > using gpsd 2.39. This uses the GPS_OPEN_R method I am not a C coder so GPS_OPEN_R does not ring a bell. > post your default.vik here. I attached it. Basically it's just a osm mapnik layer and the gps layer. > post your exact sequence of mouse/keyboard input. Well, it just happens after hitting ctrl+ and ctrl- several times. It crashes sometimes after 5, sometimes after 10 or more zooms, or it even takes more, I do not see a regular pattern for that. > Edit the src/Makefile and remove the compiler O2 directive then, make clean > && make - might give more of a chance of a backtrace. Yes, now it segfaults sometimes (using the --sync switch) > Also try running viking with the args -d -V for maximum output. I now used only --debug since --verbose gives too much output. > Understanding the cause of the 'Fatal IO error 11' is probably key. Yes, probably, also I noticed that the display is sometimes flickering while osm tiles get updated after a zoom in/out. Most of my tries to crash it end with "viking: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0." with no backtrace (using gdb --args ./src/viking --sync --debug default.vik) but sometimes I also get a Segfault and then a backtrace is possible. > Possibly running with '-sync' can help with X problems. # gdb --args ./src/viking --sync --debug default.vik (gdb) run ...
