A computer creates an extended compiled code from original source code and generated debugging extension source code. The computer receives an original source code, compiles the original source code into an original compiled code including debugging information, and generates a debugging extension source code based on the debugging information included in the original compiled code. The computer inserts the debugging extension source code into the original source code to produce an extended source code, and compiles the extended source code into an extended compiled code. The debugging information includes one or more of a debugging symbol, symbolic data, a strings table, a strings list, or a cross reference between the original source code and the original compiled code. The debugging extension source code can be inserted into the original source code in a plurality of locations.
