Hello,

The macro NUM_PSEUDO_REGS refers to ``current_gdbarch'' and not 
``gdbarch''.  Hence the equation in the patch was picking up the number 
of pseudo-registers from the previously selected architecture (which may 
not even be ARM), outch!  No wonder macro's are bad :-)

The attached calls gdbarch_num_pseudo_regs() directly with the correct 
architecture.  (It also fixes a core dump that my next patch will cause ...)

Committed as fairly obvious.

Andrew
