     Type:  defect         |     Status:  new
 Priority:  Normal         |  Milestone:
Component:  ports          |    Version:  2.3.4
 Keywords:  gcc5 segfault  |       Port:  netcdf
---------------------------+--------------------------------
 The default build works, but ncarg requires a +gcc5 build which does
 not work:
 {{{
 $ port installed netcdf
 The following ports are currently installed:
   netcdf @4.3.3.1_4+dap+gcc5+netcdf4
   netcdf @4.3.3.1_4+dap+netcdf4 (active)
 $ /opt/local/bin/ncdump -h /opt/local/lib/ncarg/data/cdf/ocean.nc
 netcdf ocean {
 dimensions:
         z_t = 25 ;
         lat_t = 66 ;

         float T(z_t, lat_t) ;
                 T:lon_t = 199.8f ;

                 T:long_name = "Potential Temperature" ;

                 lat_t:maximum = 90.f ;
 }

 }}}

 After activating the {{{+gcc5}}} version, ncdump fails:

 {{{
 $ /opt/local/bin/ncdump -h /opt/local/lib/ncarg/data/cdf/ocean.nc
 netcdf ocean {
 dimensions:
         z_t = 25 ;
         lat_t = 66 ;
 variables:
 Segmentation fault: 11
 }}}

 Other programs (e.g., ncl) also give the {{{Segmentation fault: 11}}}.
