Clang 8 double-free bug

Hello,

I recently ran into a show-stopper bug in clang 8. The bug-report for
it can be found at https://bugs.llvm.org/show_bug.cgi?id=41810. This
bug causes destructor of captured variables in a lambda to be called
twice if an exception is thrown in its body.

The fix for it is simple, to apply commit 
https://github.com/llvm-mirror/clang/commit/08d0c133ccb1b530ed743a021dc5995fbcdaf012

In the bug report I asked for another point-release of clang 8, but it
appears they are unable to do so due to time constraints.

Could we have a fixed package at least for buster?

With regards,
Martijn Otto
