In an interactive shell (in case this matters), run bash -c 'sleep 5 &' and
it exits immediately without waiting for the sleep to complete. But ssh
user@host 'sleep 5 &' (with bash as the login shell) would wait for sleep

Variable transforms such as ${VAR@Q} do not compose with substrings
expansions, eg ${VAR:1:4}.
For example, I expected ${VAR:4@Q} to quote ${VAR:4}, but instead:
-bash: VAR: 4@Q: value too great for base (error token is "4@Q")
This is because parameter value modifiers do not compose; gen
Thanks Chet,

have to be a Spack expert, it just gives us someone

Thanks Chet,
When I apply your patch it solves the string.h issue but now I see an issue
with _stdio.h:

vsnprintf(char *string, size_t length, const char *format, va_list args)
