Apologies it took so long to get back to this I had some difficulty 
setting up the environment.

The original patch:

http://sourceware.org/ml/gdb-cvs/2010-08/msg00040.html
3b26cb4b133031280fa022e2a06e58f333ed5e8d

suppressed one too many regressions. Specifically (if you look at 
3b26cb4b133^) the regression on line 10185 when the tag is 
DW_TAG_template_value_param and DW_AT_location != NULL.

Patch attached.
