When compiled with --enable-asan the fileout_netcdf handler generates 4 test failures
207: bescmd/vdata_test.hdf.dmrpp.bescmd FAILED (testsuite.at:320) 210: bescmd/vdata_packed_linked_blocks.hdf.dmrpp.bescmd FAILED (testsuite.at:323) 216: bescmd/PointFile.hdf.dmrpp.bescmd FAILED (testsuite.at:329) 217: bescmd/vdata_test.hdf.bescmd FAILED (testsuite.at:333) 218: bescmd/vdata_packed_linked_blocks.hdf.bescmd FAILED (testsuite.at:334)
These errors are all of the same nature: runtime error: load of misaligned address
runtime error: load of misaligned address
Is this a design issue arising from using void * or is this a usage issue in the way that the fileout_netcdf is allocating memory?
Or is this problem caused by allocating variable memory as byte/char rather than unit32_t etc.??
byte
char
unit32_t
Examine and fix if feasible.
Here is the verbose test output for the failed tests:
