/*
   bug-932.c

   For a basic block that consists of only a call two al __smallc function with at least two parameters,
   the sch pointer of a basic block could be wrong, resulting in incorrect live-range for some corner cases,
   which in turn for some corner cases could result in live-range separation incorrectly assuming an
   iCode to be dead, which resulted in changes to the iCode that triggered a segfault in the z80 register allocator.
