480251 - Geolocation MaemoLocationProvider does not start GPS

Status: RESOLVED WONTFIX

(Core :: DOM: Geolocation, defect)

Description

[Doug Turner (:dougt)]

For whatever reason, when we had this bit of code in ::Startup

LocationGPSDControl *control = location_gpsd_control_get_default();

if (control && control->can_control)
     location_gpsd_control_start(control);

We crash.


I have also tried using gpsbt_start() and that either doesn't start the gps or causes a similar crash.


This is on diablo.  I have not tried it on freemantle

Attachment: test application - that works fine

gcc a.c -o gps_starter `pkg-config --cflags --libs gtk+-2.0 liblocation`

this successfully starts and stops the gps on maemo.

using the _exact_ code in mozilla crashes.

when fennec crashes, the stack is blown out and the ip is wrong.  I did manage to see a crash in the test application:

not sure if it at all related, but it might be.

dunno :(

send us some cores + fennec symbols and we can try to find someone who knows something :(
