In the routine opsinputs_fill_fillelementtype2dfromsimulatedvariable_records, there is a short piece of code that sets flags for any unused levels in a record to failed:
However, in certain circumstances (e.g. a prescribed number of model levels, which occurs for averaged sonde data), this can lead to an out-of-bounds error if numLevels + 1 is greater than the length of the second dimension of El2. In most cases nothing obvious happens (although memory corruption could occur behind the scenes), but occasionally there is a segfault.
To fix this the code can be modified to compare numLevels against size(El2, 2) and only fill in the flags if there are actually superfluous levels in El2.
