gcc and stack trace: only filename + offset displayed

[pieniek]

Hi,

I compiled gcc 4.6 and I am enjoying the new standard, but there is one 
setback: the backtrace does not contain any symbols, just file + offset. 
I can use gdb to find out what these offsets are, but it would be easier 
just to see a backtrace.

The backtrace comes from ::backtrace () call, and later would be 
demangled by ::abi::__cxa_demangle; it is called during construction of 
exception class, and during terminate if it happens.

gcc 4.6 is not the version that the system ships with, it ships with 
4.5.1. Is this caused by some changes in layout of some data, that gcc 
creates and something else (glibc?) reads?
