I think Kevin has posted a GDB patch for the crash:

  [PATCH] Fix GDB internal error by using text (instead of data) section offset
  <https://sourceware.org/pipermail/gdb-patches/2022-January/185430.html>

The bug was exposed by the loss of the .data section in libgcc_s,
presumably caused by the unwinder changes.  The GCC change is fine by
itself, it's a real GDB bug.

Thanks,
Florian
