I reported the "{<No data fields>}" issue at the gdb issue tracker:
https://sourceware.org/bugzilla/show_bug.cgi?id=27556

Managed to create a local workaround from comments made there.
It was mentioned that gcc itself may be generating improper debug information
(I think specifically nesting the frame type within a function) but as I
mentioned  over there I myself don't know for sure if this is uncommon or
actually invalid.
