Hi,

Just an FYI. leafhopper / snakefly (both aarch64) have been failing to
build HEAD since yesterday. Both are on gcc-experimental, although
alligator (which also is on latest gcc, but an x86_64), is able to build
postgres successfully.

The signature seems to match an existing GCC bug and I've updated the
thread in hopes that it gets fixed sooner. Ideally these failures should
auto-fix in the coming days.

Reference:
1. aarch64 machine builds failing since 2025/06/19 -

2. Another aarch64 builds failing since 2025/06/19 -

3. x86_64 machine builds are working okay -
