Bug#831727: g++-5: Compiling with -Og does not generate debugging symbols readable by gdb

[Kyle Bentley <kwbent@uab.edu>]

Package: g++-5
Version: 5.4.0-6
Severity: normal

When I compile a short program with -Og, gdb claims that there is no debugging symbols.

Ex:  g++ -std=c++11 -o program -Og code.cpp,
running gdb ./program produces the line

"Reading symbols from ./program...(no debugging symbols found)...done."

Clanging the same code produces debugging symbols readable by gdb.
The gdb version is GNU gdb (Debian 7.11.1-2) 7.11.1
