Dear Maintainer,

I wanted to format a list of integers in base 16, but the default output was
returned in mixed case for the letters A-F. When I added case-conversion to the
format string, maxima suddenly ends up in an infinite memory-consuming loop.
The exact same format string works in lisp within maxima.


Example:


This works as expected and prints the list as a comma-separated list of
hexadecimal integers in upper case:

while this hangs indefinitely (notice exact same string and values)


This started happening when I added the case conversion. If I remove it, the
output is as expected:
