I'm trying to build SeaMonkey 2.53.19 for openSUSE x86-64 and am getting several build errors like this:

I didn't have any similar problems building 2.53.19b1.

The problem occurs only when building with with GCC 14, which Tumbleweed recently rolled out. Building with GCC 13 (which is what I had used back when building 2.53.19b1) works.

I can't reproduce this when building SeaMonkey 2.53.21 with GCC 14, so I'm guessing that a bug got fixed either in SeaMonkey or in GCC.
