GNU Project Debugger
GNU Project Debugger, or gdb, is a command-line, source-level debugger for programs that were written in C, C++, D, Objective-C, Fortran, Java, Pascal, assembly, Modula-2, or Ada and compiled for any of a number of different target architectures including x86, x86-64, IA-64, Alpha, ARM, Motorola 68000, MIPS, PowerPC, SPARC, and others. gdb supports hardware breakpoints, conditions, core dump analysis, expression evaluation, remote debugging, stepping into/out of code, disassembling, and, in some cases, reversible debugging.
