Summary: Stack unwinding is insufficient on Linux x86_64.
(-fomit-frame-pointer)

Here is the catch:
Druntime's stack unwinding code relies on frame pointers.
Optimized gcc code (at any opt. level > 0) doesn't contain frame pointers.
(Unless the architecture requires it for debugging, like x86 or
-fno-omit-frame-pointer is given.)
That means that using any Linux x86-64 libraries that take callbacks into D
results in broken exception handling! Unless the maintainers of a specific
distribution added -fno-omit-frame-pointer. You cannot expect that on Gentoo
for example.
