Oh, OK. I don't really see why that is; it's plenty fast when I use it.
I guess you have a slower ARM.

That's almost certainly exception handling. Put your bp on _Jv_Throw.

On the target I have
binutils 2.18.1~cvs20071027-1
libc6 2.7-6
On x-the host I have a random binutils I checked out from trunk about
six months ago.
