#define VIGRA_PRINT_BACKTRACE_HXX
/* Quick-and-dirty way to print a backtrace upon a signal in Linux.
Especially useful if you can't use a debugger (e.g. on TravisCI).
Usage:
Make sure to compile in debug mode.
Have "addr2line" installed (was already present on TravisCI and our local machines).

int main(int argc, char** argv)
{
program_name = argv[0];
signal(SIGSEGV, &vigra_print_backtrace); // catch the desired signal
