--- Comment #1 from Ben Woodard <woodard at redhat dot com> ---
This seems to be the best representative of a class of C++ bugs. I kind of feel
like if you fix this one it will fix the other packages that I've listed below.

First note that there 12145 filtered functions and 198 variables that were
filtered out. However, the thing that I'm kind of keying off of is all the
changes to vtables.

Comparing the ABI of binaries between
arm-none-eabi-gcc-cs-11.1.0-2.fc36.aarch64.rpm and
arm-none-eabi-gcc-cs-11.1.0-2.fc36.aarch64.rpm:

======== comparing'cc1' to itself wrongly yielded result: ===========
  Functions changes summary: 0 Removed, 17 Changed (12145 filtered out), 0
Added functions
  Variables changes summary: 0 Removed, 0 Changed (198 filtered out), 0 Added
variables

  17 functions with some indirect sub-type change:

int, tree, agg_position_info*, tree_code, tree, expr_eval_ops)' at
