I think you are slightly confused. The little patch that I suggested
(and labeled untested) is not based on any previous patch. Have you
tried it without making the modifications you suggest below?

My other patch that you are refering to is the one that forces GDB
to trust %ebp in frameless functions that live in DLLs. This change
was to work-around a problem that is totally unrelated from the one
you are trying to solve.

To re-explain the logic behind the suggestion I posted here, when
we don't find the function start address (as in your case), we don't
parse the prologue. In this case, the current code will fallback on
using the default value for cache->sp_offset, which is unlikely to
be right. My suggestion instead is to trust the %ebp register, for
which we have found that we get better results (on Windows).
