Thanks to the work of the fish maintainer this now looks like it is a bug in 
either gcc or posix_spawn() or something like that:

https://github.com/fish-shell/fish-shell/issues/6878#issuecomment-640128661

A minimal testcase is here:

This is not limited to sparc32 userspace, but also affects sparc64.
