[Fwd: stack overflow "cause" found]
Xen is compiled with no -O gcc option, meaning no optimization, and the
compiler does the safest thing imaginable. This means that if a
function, say vmx_world_save(), calls the same inline a bazillion times,
the stack will have one block of local variables for each invocation of
that function!
Xen really should not be doing this. We could either uninline some of
these functions, or try gcc -O2 or gcc -Os.
Ian, Keir, which of these approaches do you prefer?...
