I install msgfmt via homebrew on MacOS 15.3.1 on a Macbook Pro with ARM
architecture. The installed version is 0.25. When I run 


msgfmt -c test.po


with a file test.po that contains


msgid ""
msgstr ""
"Project-Id-Version: pspp-2.0.1\n"


then msgfmt crashes with


MacBookProM4:pspp fritz$ msgfmt -c test.po 
test.po: warning: Charset missing in header.
                  Message conversion to user's charset will not work.
Segmentation fault: 11
MacBookProM4:pspp fritz$ 


When I have a longer po file with correct header, then msgfmt just crashes. So
this is minimum crash example. Without option "-c" I do not see a segmentation
fault. This occured during compilation of pspp on MacOS. The po files and hole
compilation setup is quite old. But this is the first time I tried this on an
ARM system. I attached the test.po file.
