Dear maintainer,

I've prepared an NMU for libunwind (versioned as 1.8.1-0.1) and
uploaded it to DELAYED/2. Please feel free to tell me if I
should delay it longer.

Thanks
noah

Control: reassign -1 src:libunwind 1.7.2-1

Reassigning this from the libunwind binary package (which, confusingly,
is part of the llvm-toolchain-* family) to the libunwind source package
(which is what Noah NMU'd).

Please see <https://bugs.debian.org/1093709> for the nmudiff.

Hi,

I also ended up NMUing libunwind. Here is my diff:

From 5dff90a8af00aeeb8db2215d3bf05453b81719a2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] NMU libunwind/1.8.1-0.3 disabling C++ exception support

Disable C++ exception support for all architectures.

 * hppa maintainer John Dave Anglin reported it (and other things) as
   broken via #1107618 and requested it to be disabled.
 * python-memray autopkgtests segfault (#1122076) when libunwind is
   lazy-loaded, because its semantics do not match gcc's, whose symbols
   it overrides.
 * There is another x86 segfault reported upstream (#1130107) where
   disabling C++ exception support makes the problem go away.
 * It was originally enabled in Debian to support clang/llvm (#923962),
   but that ends up using its own libunwind.
 * Fedora disables C++ exception support.
 * libunwind upstream recommends disabling it.
https://github.com/libunwind/libunwind/issues/405#issuecomment-1209587993
 * I ran autopkgtests for all rdeps with C++ exception support disabled
   and none of the failures is to be attributed to this change.
