39 /* Quick-and-dirty way to print a backtrace upon a signal in Linux.
40
41 Especially useful if you can't use a debugger (e.g. on TravisCI).
42
43 Usage:
44
45 Make sure to compile in debug mode.
46 Have "addr2line" installed (was already present on TravisCI and our local machines).
47
48 #include <vigra/print_backtrace.hxx>
49
50 int main(int argc, char** argv)
51 {
52 program_name = argv[0];
53 signal(SIGSEGV, &vigra_print_backtrace); // catch the desired signal
54
55 run_buggy_code();
56 }
