>Organization:
>Environment:
RedHat 7.0 with GDB 5.1.1
>Description:
Using included files for function, GCC seems to generate incorrect file information for the addresses coming from the included file. GDB doesn't seem to be at fault as a cross-compiled GCC/GDB (ARM ELF32/DWARF) seems to work fine.

The problem is either at GCC generated debug information or GDB reading the debug information.
>How-To-Repeat:
Unzip and compile:
gcc -g -o test test.cpp

Debug using GDB, break at main, and step a couple of lines. This is the output from GDB:

Line number 5 out of range; test.cpp has 4 lines.

>Fix:
Correct the line generation table.
