mat failures with macOS 14's iconv

Using c081296 on arm64osx on macOS 14.3 and a6osx on macOS 14.2.1, the following mats fail:
Bug in mat iconv-codec clause 6 at line 710, char 7 of ../../mats/io.ms
Bug in mat iconv-codec clause 14 at line 1004, char 7 of ../../mats/io.ms

Bug in mat iconv-codec clause 14 at line 1004, char 7 of ../../mats/io.ms
The mat for codec GB18030 on line 710 of io.ms fails when make-codec-buffer returns a 4-byte buffer instead of the default 1024-byte buffer. Apparently this iconv-based codec needs more bytes. At 17 bytes it passes.
The mat for codec UTF-8 on line 1004 of io.ms fails unconditionally. It also fails using Chez Scheme 9.5.8 on a6osx, so I think the problem may be due to a change in macOS 14's iconv.
These mats pass on macOS 12, so I suspect the problem involves the newer iconv in macOS 14.
When I install libiconv using Homebrew on macOS 14 and configure Chez Scheme to link against it, all the mats pass.
There are many reports about macOS Sonoma iconv compatibility issues.
