Test iconv__iconv1 FAILED: Test character for which there is no transliteration

Hi, I'm attempting to run the test suite here and I'm seeing one failure in the iconv tests. Everything else passes.

This is using glibc 2.39, with the following locales enabled:

C.UTF8 UTF-8
en_US.UTF-8 UTF-8

The failing test is:

Start by reproducing the iconv__iconv1 failure from the test suite with glibc 2.39 and the listed locales, then inspect test.adb around line 61 and the surrounding iconv test cases. Done means the character-without-transliteration case passes while the other iconv assertions remain passing.
