==17348== Warning: invalid file descriptor 1024 in syscall close()
Your exe is probably trying to ensure all file descriptors are
closed. You should probably use getrlimit() to query the upper limit
rather than assume anything. Exes under Valgrind have a slighly lower
limit because Valgrind uses some file descriptors itself (e.g., its
log file).
See also the manual page for 'close_range', which is a system call in
Linux >= 5.9 and FreeBSD.
You may have to think about what the parameters should be, but
'close_range' is very efficient.
Ahem. Someone needs to implement close_range for FreeBSD in Valgrind.
Something else for 3.22.
A+
