[Wine] What constitutes a good backtrace?

[Charity Abbott]

According to Gentoo...
Note: Some packages unfortunately handle stripping by themselves,
inside the upstream provided makefiles. This is an error and should be
reported. All packages should leave Portage the task of the stripping
or simply restrict stripping entirely. The main exception to this are
binary packages. They are usually stripped by upstream, outside of
Portage control.

Wine seems to be one of these packages. I tried it myself. However,
they provide winedbg and it is included in the Gentoo package. Did you
try running that?
