I think gdb raises this sigabort with help of libc. So it was initiate by yourself.

To get more information you need to recompile fcamera without code optimization, so without -O2 and activate debug information -g or -g3. Furthermore you should avoid to strip your binary.

If you are in doubt please post your makefile. The binary get stripped by dpkg, when compiling a deb file (rules: dh_strip). So don't make a deb only compile fcamera with right gcc flags and copy the binary.

For gcc flags it could be enough to change in the project file:

to

After the change you need to generate the makefile again and compiling. Try to run it again with gdb and see if you get more informations.
