Currently `Debug` only prints the raw value: ExitStatus( unix_wait_status( 139, ), ) That isn't very meaningful on its own since you may have to manually decode the value to understand what happened. Change the implementation to also include the `Display` representation, which provides more user-friendly details. ExitStatus( unix_wait_status(139, "signal: 11 (SIGSEGV) (core dumped)"), )

Update subtree sync docs

…round Remove /tmp workaround now that rustdoc fixed the disk usage issue

…ytes API to reduce RAM usage

Remove integer packing workaround and replace by the new_array_from_bytes API to reduce RAM usage

Use correct alignment for global variables

Make const strings readonly and remove the pointer indirection

…ures Fix to use target features from a target spec

and Extend for String too
