I feel like that could happen in several cases, we should probably fix that VOL callback to handle const and non-const

Agreed. Just thought I'd temporarily disable it until we can do that. I'd like to eventually search for all the places we've turned things off with H5_GCC_CLANG_DIAG_OFF in the past and correctly fix things if we can, but that's for a later date.
