Package: gnudatalanguage
Version: 0.9~rc1-1.1
Severity: important
Inquiring a NetCDF variable with more than one dimension leads to an
assertion error in dstructgdl.hpp when the tag DIM is initialized as
GetTag(tIx)->N_Elements() == 1 and data.N_Elements == 2 (in fact the real
dimension)
gdl: dstructgdl.hpp:380: void DStructGDL::InitTag(const std::string&,
const DataGDL&) [with DataGDL = Data_<SpDULong>]: Assertion `GetTag(
tIx)->N_Elements() == data.N_Elements()' failed.
This renders the package nearly unusable if you are dealing with NetCDF
files.
Here is a simple program code to reproduce the error
------------ snip here ------------
fid = NCDF_OPEN('simple.nc')
; getting the variables is ok
NCDF_VARGET, fid, 0, test1d
NCDF_VARGET, fid, 1, test2d
PRINT, '1d'
PRINT, test1d
PRINT, '2d'
PRINT, test2d
; inquiring 1d-variables is ok
inq1d = NCDF_VARINQ(fid, 0)
PRINT, '1d'
PRINT, inq1d
; but inquiring 2d (or nd) variables fails with an assertion error
inq2d = NCDF_VARINQ(fid, 1)
PRINT, '2d'
PRINT, inq2d
END
------------ snip here ------------
and the NetCDF file can be produce by running
ncgen -o simple.nc simple.txt
with simple.txt being the following:
------------ snip here ------------
netcdf simple {
dimensions:
x = 2 ;
y = 2 ;
variables:
int test1d(x) ;
test1d:long_name = "test1d" ;
test1d:standard_name = "test1d" ;
int test2d(y, x) ;
test2d:long_name = "test2d" ;
test2d:standard_name = "test2d" ;
data:
test1d = 1, 2 ;
test2d =
1, 2,
3, 4 ;
}
------------ snip here ------------
