[jitrino]assertion error

[Estelle Liu]

Hi,all.
  We tried to insert an instruction in HIR, and when the instrumented code
run into Ia32RegAlloc2, the assertion  "assert(pspans[i].beg != 0);" in
method RegAlloc2::Opand::update() failed. I wonder the possible reasons to
result in this occasion, could anyone give some suggestion?
Thanks very much!
