Generating PDB files for release executables does not affect any optimizations, or significantly alter the size of the generated files. Typically, the only difference is the path, and the file name of the PDB file is embedded in the executable. For this reason, you should always produce PDB files, even if you don't want to ship them with the executable.
If you are concerned about people using the PDB file information to help them reverse engineer your executable, you can also generate stripped PDB files, by using the /PDBSTRIPPED:filename linker option. If you have existing PDB files that you would like to strip private information from, you can use a tool called pdbcopy, which is part of the debugging tools for Windows.
If functions on the current stack were compiled by using the Omit Frame Pointers (/Oy) optimization, and if symbols are not present, the debugger cannot reliably determine which function called the current function. This is because without the Frame Pointer Optimization (FPO) information that PDBs contain, the debugger cannot rely on the frame pointer register (EBP) to point at the saved previous frame pointer and at the return address of the parent function. Instead, it guesses. Sometimes it gets it right. However, it often gets it wrong, which can be misleading. If you see a warning about missing symbols, or no symbols loaded, as in the following example, do not trust the stack from that point down.
In many cases, it's possible to continue debugging without symbols, because the problem is in a location that has accurate symbols, and you don't need to look at functions further down the call stack. Even if a library that is in your call stack doesn't have PDBs available, as long as they were compiled with frame pointers, the debugger should be able to guess correctly at the parent functions. Starting with Windows XP Service Pack 2, all Windows DLL and executable files are compiled with FPO disabled, because it makes debugging more accurate. Disabling FPO also allows sampling profilers to walk the stack during run-time, with minimal performance impact. On versions of Windows before Windows XP SP2, all operating system binaries require matching symbol files that contain FPO information, to allow accurate debugging and profiling.
If you debug 64-bit native executables, you do not need symbol files to produce valid stack traces, because x64 operating systems and compilers are designed not to require them. However, you still need symbol files to retrieve the function names, call parameters and local variables.
However, some cases are particularly difficult to debug without symbols. For example, if you debug a program for which you built a PDB file, and if you crash in a callback from a function in a DLL that you don't have symbols for, you will not be able to see which function caused the callback, because you will not be able to decode the stack. This frequently happens in third-party libraries, if PDBs are not provided, or in old operating system components, if PDBs are not available. Callbacks often happen during message passing, enumeration, memory allocation, or exception handling. Debugging these functions without an accurate stack can be frustrating.
To reliably debug mini-dumps that are generated on a different computer, or that crashed in code that you do not own, it's important to be able to access all the symbols and binaries for the executables that are referenced in the mini-dump. If the symbols and binaries are available from a symbol server, they are automatically obtained by the debugger. For more information on mini-dumps, see the Crash Dump Analysis white paper.
