General Bug Reports in Gentoo Linux

Bugs come in many forms like emerge failures or segmentation faults. Whatever the cause, the fact still remains that such a bug must be fixed. Here is a few examples of such bugs.

Code Listing 1.1: A run time error

$ ./bad_code `perl -e 'print "A"x100'`
Segmentation fault

Code Listing 1.2: An emerge failure

GDB, or the (G)NU (D)e(B)ugger, is a program used to find run time errors that normally involve memory corruption. First off, let's take a look at what debugging entails. One of the main things you must do in order to debug a program is to emerge the program with FEATURES="nostrip".
