During compilation of Zig, using the standard posix instructions, the zig0 executable segfaulted when it was run.

Running the zig0 executable by itself also segfaults.

Compilation log:

    I get a different error on Android x86_64 (Waydroid):

    Edit: Seems to be a different issue (see #16565), as "Debian 10 in proot" should be still Linux I think
