The problem here is that the threader is coming up with a path where the only valid result is a NAN. When the abs op1_range entry is trying to add the negative posibility, it attempts to get the bounds of the working range. NANs don't have bounds so they need to be special cased. PR tree-optimization/107355 gcc/ChangeLog: * range-op-float.cc (foperator_abs::op1_range): Handle NAN. gcc/testsuite/ChangeLog: * gcc.dg/tree-ssa/pr107355.c: New test.
