--- Comment #7 from Nils Gladitz <nilsgladitz at gmail dot com> ---
(In reply to Nils Gladitz from comment #5)

I reported the "{<No data fields>}" issue at the gdb issue tracker:
https://sourceware.org/bugzilla/show_bug.cgi?id=3D27556

Managed to create a local workaround from comments made there.
It was mentioned that gcc itself may be generating improper debug informati=
on
(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.=
