I get a reproducible crash in the Neumann scene in Luxmark 3.1.

ASSERTION FAILED: insn2.header.opcode == GEN_OPCODE_NOP
  at file /build/beignet-JxAr70/beignet-1.1.2/backend/src/backend/gen_encoder.cpp, function virtual void gbe::GenEncoder::patchJMPI(uint32_t, int32_t, int32_t), line 1043

Possibly the same as bug 94810.

Googling the error also found similar (unreported?) bugs:

No more crashes with 1.3.2. Image validation fails, but I will file new bugs for those problems.
