--- Comment #4 from dodji at redhat dot com ---
Hello,

So clang and mozilla in particular have binaries that are so huge that I th=
ink
they'll need some very specific work for libabigail to handle them.  For
instance, just dumping the debug info of the libclang-cpp.so yields a file =
of
more than 20GB.  That is insane.  Just analyzing that in the current mode of
operation takes an herculean machine, at least.

I'll defer that work for later when we have more bandwidth, not because I d=
on't
like clang, but because I think we can be helpful to many many many more
projects of realistic size in a shorter period of time.

Trying to read the binary however should not crash.  So I'll look at it
somewhat, but I won't be able to spend a lot of time on it for now.  I just
wanted to let you know about this.  I believe there is a bug opened for the
support of clang binaries (huge huge quasi pathological c++ binaries really=
),
if I am not mistaken.  If not, I think we should open one.
