The configure option --with-regex results in use of the bundled regex library instead of the system-supplied one. The bundled library has at least one potential defect, so it is probably better to remove this option and use the one from the GNU C library. See also

Additional info:
* package version: mutt 1.10.1-4

Thanks for bringing this to our attention. Before taking any action I'd like to wait for upstream's reply to your bug report. Please let us know when you hear from them. Cheers.

There has not been an upstream reply yet, but arguments in favour of removing the option:
- Internally the standard POSIX regex interface (regecomp, regexec, etc.) is being used.
- The bundled version is derived from the GNU C Library, but is not really maintained (except for some build fixes, there has not been changes this millennium).
- While some esoteric operating systems might lack a good regex library, this is not the case for Linux (which has GNU libc).
- Other distributions (Debian, Fedora) do not have this option. (Gentoo does though, probably due to the misleading name that suggests enabling a feature)

You win! The second argument convinced me.
