I am sorry - could you please refer to that case?
it is interesting to see if the problem doesn't lie in some obfuscated
bug withing build tools. In my experience valgrind complains about so
much of the code shipped, especially on non-i386 architectures
obviously. Some incorrect memory read/write could successfully pass
without segfaulting on real but fail on emulated machine, or vice
versa - just a matter of luck. That would not invalidate build process
on emulated box, imho I would even consider it another QA test more for
the build tools involved than to QEMU ;)
