By looking at the local alloc verbose output, it seems that call->dreg is virtual (never assigned a machine register) and that it gets %eax because it happens to be the first free register. Am I missing something?

The destination register is marked with 'a' in the cpu description: this
is considered by the register allocator to be the EAX register.
The 'a' marker was only on the regular calls, though: I fixed it to
include call reg and call base+offset.
