------- Comment #3 from rguenth at gcc dot gnu dot org 2010-04-01 13:39 -------
The issue seems to be the C++ frontend marking inline functions needed
at cp/semantics.c:3452 while the middle-end should already take care
of that in cgraph_decide_is_function_needed.
Somehow that confuses us and we end up performing inlining on a body
that has been reclaimed.
Honza?
The following "fixes" it, bug arguably the bug must then be latent
with dllexport.
