Building for debug on a supported platform with the currently shipping version
on the complier should work, or it should be listed as a known issue in the
release notes.

Anyway, the problem may not be the dwarf version, but undefined references. In
the clean build output (see attachment 2941), the dwarf version warnings are
preceeded by the following:
