The recently released Gdb 7.10 added support for writing a frame unwinder in Python,
which is ideal for us.
doc: https://sourceware.org/gdb/current/onlinedocs/gdb/Unwinding-Frames-in-Python.html#Unwinding-Frames-in-Python

The issue tracks that.

@minux minux added this to the Go1.6 milestone Aug 29, 2015

Is it a duplicate of #17575 where @aclements provided a sketch?

See also #16638 (using frame pointers for unwinding in the runtime).

@minux, are you proposing any additional things we could do with a custom unwinder besides work correctly on core files (which issue #17575 tracks)?
