Extended Description

sac2c segfaults in Variable Propagation when compiling the attached code from the testsuite. Reason is a broken syntax tree left by IVE as properly detected using the treecheck facility:
  **** Generating full with-loop partitions ...
  **** Inferencing with-loop reuse candidates ...
  **** Annotating offset variable at with-loops ...
  **** Eliminating index vectors (split selections) ...
  **** Eliminating index vectors (split loop invariants) ...
WARNING: mandatory son LET_EXPR is NULL
  **** Propagating variables (for IVE) ...
OOOOOOOPS, your program crashed the compiler 8-((
