While you aren't asking why, 'file' is initialized to null and is not a stack
allocated class as it would be in C++.
The first step to debugging is to use the -gc flag instead of -g. The
unreleased version of GDB has the patch for D mangling, otherwise you need the
symbols to mimic C. Then you can run your program with GDB.
As you should be familiar with. You can get the stack trace form GDB if you
enable core dumps: $ ulimit -c 5000 && dmd -gc test.d && ./test && gdb ./test
core
