very slow gdb stepping.

[Paweł Sikora]

Hi all,

during debugging a large c++ application an each gdb step (next or step-in)
takes from ~2 to ~30 seconds which is horribly slow and uncomfortable :(
the callgrind shows some hot places in gdb: http://carme.pld-linux.org/~pluto/gdb-cpuhog/callgraph.png

callgrind results from ~30min session and .rpms are stored here:
http://carme.pld-linux.org/~pluto/gdb-cpuhog/

is it a known issue?
