Joseph's patch doesn't work for me, because the --stack parameter never makes
it to the link line for some reason, and I get the same crash building
cipher.o. This is the relevant output of bootstrap:

In my project, we have 3 components: test,libbar.so and libfoo.so. libbar.so
depends on libfoo.so,and test depends on the two .so. In libfoo.so, I throw an
exception, but libbar.so can't catch it.

I think the first thing is to figure out what mangling we want for these
things and if they should be mangled at all. The C++ ABI doesn't specify a
mangling for these operators,
On current x86 and x86_64 processors denormal numbers are handled as a special
case and very slowly. This can have a detrimental impact on the performance of
numerical programs. A common fix for this problem, at the cost of some
numerical stability, is to set the processor flag to flush denormals

-ffast-math also enables other (even more unsafe?) optimizations which may not
be desirable.

In fact, using modified_between_p would not fix the bug. The problem is that
use_killed_between gives the wrong answer *before* it reaches the code that
redoes modified_between_p using df data structures.

I don't think this is a bug as the typeinfo of ebase in libbar is being marked
as hidden (local) so you have two different typeinfo that are not merged at
