[Nek5000-users] prex segmentation fault

[nek5000-users at lists.mcs.anl.gov]

Hello all,

I am running into a segmentation fault when using "prex" on my 32 bit
laptop.  This occurs when using both the gfortran and ifort compilers.
More info below, the first is from the Intel compiler, the second from
gfortran.
