Workaround:
Rearranging the members of the struct so that the largest members come last might keep the offsets of all members below 16MiB. Alternatively, compile without DWARF information.
Release Notes:
For very large structs with any member where offsetof(struct,member)>=16MiB, the DWARF information would incorrectly sign-extend the value in the DW_AT_data_member_location attribute.
