To help isolating bugs that cause crashes, backtraces can be very useful. To make a backtrace, run
gdb asc run
and make ASC crash. Then type
and send the output to firstname.lastname@example.org. If you want to run ASC with command line parameters, pass the parameters to the run command.
In order to obtain a useful backtrace, you must have compiled ASC yourself with debugging symbols enabled. If debugging symbols were disabled, gdb will tell you something like no debugging symbols found or similar.
To enable debug symbols, type
EXPORT CXXFLAGS="-g" EXPORT CFLAGS="-g"and rebuild ASC with
make clean configure makeand, if desired, make install
If your computer is powerful enough ( >= 1 GB memory, > 1000 MHz), running valgrind is very helpful:
Valgrind lets the application run in a kind of virtual machine and analyzes its memory. The whole task requires tons of memory and slows ASC down by an order of magnitude, but the results are invaluable when the error is related to memory corruption.
