Bundled components gcc and gdb are incompatible

[GoogleCodeExporter]

Incompatibilities between gcc-4.4.0 and gdb-5.2.1 of the MinGW toolchain
bundled in this version of Python(X,Y) cause Eclipse's debugger to hang
indefinitely when debugging C/C++ programs.

Version: 2.6.5.1
Components Installed: Full (all)
Installation Directories: default path
Target Users: All users
OS: XP
Logged in as: Administrator
Cleaning prior to installation: N/A -- Python(X,Y) was not previously
installed.

To reproduce the problem:
1. Installed Python(X,Y)-2.6.5.1 for all users, and with a full complement
of options.
2. Launch Eclipse
3. Create a Hello World C or C++ project.
4. Attempt to debug the resulting binary executable program.

The expected output:
Proper operation of the debugger.

What I see instead:
The debugger hangs indefinitely.

Additional information -- (two sections: Another Symptom and Possible Fix):

Another Symptom:
The following error message from gdb sheds some light on this issue:

$ gdb hello_world
GNU gdb 5.2.1

This GDB was configured as
"i686-pc-mingw32"...c:/cygmnt/prj/pkg/src/gdb/mingw32/gdb/dwarf2read.c:985:
gdb-internal-error: read_comp
_unit_head: dwarf from non elf file

An internal GDB error was detected.  This may make further
debugging unreliable.  Quit this debugging session? (y or n) n

Create a core file containing the current state of GDB? (y or n) n

(gdb) quit

Possible Fix:

Replacing the MinGW gdb installation with gdb-6.8-mingw-3.tar.bz2 seems to
correct the issue.
