sac2c-d revision 16651
Compile tvdnd_abstract with:
sac2c-d -O3 -v1 -maxlur 10  -L fluid -mt tvdnd_abstract.sac -DDIM=2 -o tvdndnd_abstract_mt -v3 -dtreecheck
I need to add the -mt switch to get the  error:
** 19: Generating Code ...
  **** Tag preparation ...
  **** Converting to old type representation ...
  **** Creating intermediate code macros ...
ASSERTION FAILED: file 'codegen/compile.c', line 7087
if-clause condition is neither a N_id nor a N_bool node!
EXECUTION TERMINATED
The sac source file is attached.
