If I remember from our discussions, if `SymbolFileDWARFDebugMap::LinkOSOAddress` succeeds, then we're surfacing the linked binary's Section and offsets.  It's only in this unusual case you found, where a function exists in the .o file that didn't make it into the linked binary and we've picked this .o file's copy of this function, where we get into this pickle and fall back to trying to use the .o file's Section and offset, which immediately leads to the bug you found.
