Understanding SIGSEGV issues

[Russel Winder]

So I have a D program that used to work. I come back to it, recompile it, and:

|> dub run -- ~/lib/DigitalTelevision/DVBv5/uk-CrystalPalace__RW 
Performing "debug" build using /usr/bin/ldc2 for x86_64.
libdvbv5_d 0.1.1: target for configuration "library" is up to date.
dvb-tune ~master: target for configuration "application" is up to date.
To force a rebuild of up-to-date targets, run again with --force.
Running ./bin/dvb-tune /home/users/russel/lib/DigitalTelevision/DVBv5/uk-CrystalPalace__RW
Device: Silicon Labs Si2168, adapter  0, frontend  0
Program exited with code -11

(gdb) r ~/lib/DigitalTelevision/DVBv5/uk-CrystalPalace__RW
Starting program: /home/users/russel/Repositories/Git/Masters/Public/DVBTune/bin/dvb-tune ~/lib/DigitalTelevision/DVBv5/uk-CrystalPalace__RW
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Device: Silicon Labs Si2168, adapter  0, frontend  0

Program received signal SIGSEGV, Segmentation fault.
__GI___libc_free (mem=0xa) at malloc.c:3093
3093	malloc.c: No such file or directory.
(gdb) 

Can anyone give me any hints as to where to start even getting a glimmer of an
understanding of WTF is going on?
