Mathis, > We stumbled across a problem with netcdf-4.1.1-rc1 on our 64bit BE machine > (Power6). The symptom was that ncdump showed corrupted dimensions for > perfectly normal netcdf4 files. ncdump linked with netcdf-4.0.1 was okay. > > In 4.1 you changed the type of len in struct NC_DIM_INFO from int to > size_t. This creates problems with sscanf in read_scale() on our machine. I > attached a patch to fix this. Before applying your patch, running on a 64bit BE machine and building zlib, hdf5-1.8.4-patch1, and netcdf-4.1.1-rc1 all in 64-bit mode (-m64 compiler flag) resulted in 18 of 55 tests failed with "make check" in libsrc4. After applying your patch we reduced that to 2 of 55 tests failed: *** Testing file with just one very long dimension...Sorry! Unexpected result, tst_dims.c, line: 1010 Sorry! Unexpected result, tst_dims.c, line: 1018 2 failures *** Testing reference file with just one very long dimension...Sorry! Unexpected result, tst_dims.c, line: 1057 1 failures 3 errors detected! Sorry! FAIL: tst_dims *** Testing interoperability between big vs. little endian platforms. *** testing with file with lots of atts...ok. FAIL: tst_interops4 So we still have work to do, but it will have to wait until Ed gets back next week.
