GDB 7.7.1 is only advisable if gdb 7.2 can not be made working at all. I advice trying the setting from the link first. That is with the exception of some, but not all systems running win 7 or up. (Those issues do afaik only happen on some systems, seems to depend on other software installed, but not known for sure) If gdb 7.2 crashes on your platform, then 7.7 may be more stable.

Unfortunately testing gdb (up to 7.8.1 so far) all newer versions had regressions. The only newer version that was in some form usable is gdb 7.7.1. This is available as separate download.
