Is there any reason why not to strip symbols from executable?

Question

A couple of years ago I asked a question how to reduce size of executables. Using MinGW compiler, stripping symbols (-s option) helped to reduce 50%+ of the size.

Answer 1

There is no good reason to strip symbols. By stripping symbols, for instance, you will eliminate a possibility to gather process stack - an extremely usuful feature.

EDIT. Several people here seem to be confused about the difference between debug symbols and 'general' symbols. The first are only produced when -g (or similar) option is given to the compiler, and are usually used only in debug builds (though can be used with optimized builds as well). The regular symbols are things such as function names, and are produced by compilers so that object files could be linked, or .so files loaded. There are several extremely useful non-invasive tools which can be used on non-debug running executables which depend on symbols being non-stripped.
