The issue was the SysTick timer, which was configured by the bootloader to blink the backlight LEDs, but was not de-configured before booting to the application. Without the SysTick timer de-configured, the FreeRTOS tick timer, which relies on the SysTick timer, fired before FreeRTOS could be properly configured. Since the FreeRTOS SysTick handler contains some OS-specific functions and data, the fact that these were not initialized probably led to a segfault. This issue was fixed in boot.c, by de-configuring the SysTick timer.

Some open-field testing needs to be performed on GPS reception, as the GPS readouts are ~1 arcsec. off from reference Android app (`My GPS Coordinates'). However, this does translate in 30m accuracy, so it's not a big deal.

Note: the application still doesn't show the coordinates, just UTC time received from sattellites.

This was actually wrong, the Antenova M10478 GPS module doesn't need a double ON_OFF pin pulse, it just needs an ~150ms delay from the time its EXT_RST pin is asserted to the time it can dump out data. What was happening before is that we didn't have a delay in the gps_init function before sending the on_off pulse, and this meant that the pulse was missed by the module, which never turned on. The added delay fixes this issue and we now need only a single pulse.
