Unfortunately there is, yes. In fact there tends to be less address
space available on AMD64 than on x86 because of limitations on what
address we can load valgrind at.

We do have a plan to fix this so that the address space does not have
to be rigidly partitioned between valgrind space and client space.

That's a bit nasty. Can you run with --trace-syscalls=yes and see
what the last system call it executed before that assertion was?
