buexs0.F:10:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [all] Error 1
Interestingly, if we change name of the variable IBUFR to some other, for
example BUFFER, a different compile time error occurs.
