Hi Joel,
I think we've found the cause of your bug which doesn't appear with the
pgf compilers we normally use but does appear with gfortran.
The fix is to change cg/cns/src/godunov/dudr3d.f lines 409-410
and change the variable "pressure" to the variable "pp"
call getp3d (md,rwk,pp,dp,0,te,ier)
if (pp.le.0.d0) then
As a remark, you will learn more from gdb if you compile the files
with the -g flag (e.g. the file dudr3d.f) You can turn on compilation
with -g in the cg/cns/Makefile with the flag
compile=dbg

Hi Bill,
I just compiled the new version of cns godunov (v23), but I am still getting
the same segmentation fault error as in the previous version (v22). Here is
the output of gdb,
Program received signal SIGSEGV, Segmentation fault.
