Debugging with GDB Manual The GNU Source-Level Debugger (769148-001, March 2014)

GDB circumvents the error by ignoring this symbol
information. This usually allows you to debug your program,
though certain symbols are not accessible. If you encounter
such a problem and feel like debugging it, you can debug
(gdb) with itself, breakpoint on complain, then go up to
the function read_dbx_ symtab and examine *bufp to
see the symbol.
stub type has NULL name GDB could not find the full definition for a struct or class.
const/volatile indicator missing (ok
if using g++ v1.x), got...
The symbol information for a C++ member function is
missing some information that recent versions of the compiler
should have output for it.
info mismatch between compiler and
debugger
GDB could not parse a type specification output by the
compiler.
