The code is well protected against such issues. If one of our base structures
become larger than corresponding predefined structure, the compiler should
trigger an error similar to:
In file included from
../../../ompi/ompi/datatype/ompi_datatype_create_contiguous.c:23:0:
../../../ompi/ompi/datatype/ompi_datatype.h:105:10: error: size of array
'padding' is too large
char padding[PREDEFINED_DATATYPE_PAD - sizeof(ompi_datatype_t)];
^
This is the case for all types that have a predefined enveloppe. Thus, the
commit 30268 was unnecessary as the check was already included in the
compilation by the inclusion of the ompi_debugger_canary.c.
