Questions tagged [debug-symbols]

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module.

A debug symbol is information that expresses which programming-language constructs generated a specific piece of machine code in a given executable module. Sometimes the symbolic information is compiled together with the module's binary file, or distributed in a separate file, or simply discarded during the compilation and/or linking. This information enables a person using a symbolic debugger to gain additional information about the binary, such as the names of variables and routines from the original source code. This information can be extremely helpful while trying to investigate and fix a crashing application or any other fault.

I have a straight-up application -- no web services, or even calls to IIS, no UI, nothing -- just takes input data, munches it, then returns a result. Over the course of 15 trials, debug takes a little over nine minutes(!) to load the symbols before…
