If, as you suggest, a second step (s command) would take me into the
virtual function, I could live with the (minor) problem, but here the
first step command takes me to the closing } of the virtual function
(although if this is random as you suggest, it might not be significant)
and the second step (s) command takes me to the next statement after the
virtual function call, jumping it completely. Very inconvenient.

In order for me to try and replicate your behaviour, could you give me
some details?

I am running the very latest GNU gdb 2002-07-09-cvs, gcc 3.1 and I
compiled the example with
	gcc -g3 -lstdc++ thunk.cpp
