Excellent! I can stop trying to dig in to the code and understand where all the word expansions happen.So strange to find those one off bugs, and great that it was only one. Do you have, or working on a patch that can be applied to a build?
It will be in the next devel branch push. If you want to try to apply it
to the source yourself, here it is:
*** ../bash-5.2-patched/subst.c Thu Feb 22 11:08:16 2024
--- subst.c Thu Jan 9 15:08:52 2025

if ((flags & SX_NOCTLESC) == 0 && c == CTLESC)
{
! i += 2;
CHECK_STRING_OVERRUN (i, i, slen, c);
continue;
}

if ((flags & SX_NOCTLESC) == 0 && c == CTLESC)
{
! i++;
CHECK_STRING_OVERRUN (i, i, slen, c);
+ ADVANCE_CHAR (string, slen, i); /* CTLESC can quote mbchars */
+ CHECK_STRING_OVERRUN (i, i, slen, c);
continue;
}
It's in subst.c:string_extract_verbatim().
