It sounds like the symbols in the symbol table don't have valid sizes when they really should. What kind of executable are you debugging? A PECOFF file? If so, you should take a look at and fix the code in:
What we do for mach-o is to parse the symbol table first and then run back through all symbols, and any symbol that have a size of zero, set their sizes to the delta between the current symbol and the next addressed symbol. Since the symbols are usually out of order address wise, we run through all symbols that have addresses and add their indexes to a std::vector, then sort the vector of address indexes, and then we can do the above fixups.

I can manually read the symbols address space but the symbol also has no end_addr set which makes it difficult to tell where the symbol ends .
