New Issue: [Bug]: assert due to zero length string

28289, "jabraham17", "[Bug]: assert due to zero length string", "2026-01-09T23:14:58Z"

The following program results in an assertion failure due to a nullptr

var sep = "";
write(sep);
Assertion failed: (dest != NULL && src != NULL), function chpl_memcpy, file chpl-mem.h, line 165.
zsh: abort      ./a.out

This aborts because we are trying to copy something to a nullptr dest
