--- Comment #3 from Julian Seward <jseward acm org>  2009-03-01 22:21:39 ---
DW_OP_ 0x93 is DW_OP_piece, which is used to describe a variable
which has been split into pieces and the pieces stored in 
different locations.  eg a 64-bit value in two 32-bit registers.
Figuring out what the right thing to do here is not a 10-second
operation.

The offending DW_OP_ is in libm-2.8.so.debug in this case.  
A quick workaround might be to strip the debuginfo from libm.

To see the DW_OP_piece expressions, do
readelf -wi libm-2.8.so.debug | grep DW_OP_piece

Deferring until after 3.4.1 release.
