The declaration would be the "specification DIE" (i.e., the DIE referred
to by the DW_AT_specification attribute) and that's where it was.
You moved it to the definition DIE.

It is more likely that old GDB errored out because Clang now uses DW_TAG_member
to declare static members inside a class, instead of DW_TAG_variable.

GCC 4.4.3 has it on the declaration DIE.
