I may have found something.

Would you please check if on the affected system, ther is a
gconv-modules.cache file somewhere under /usr?  Fedora uses
/usr/lib64/gconv/gconv-modules.cache, for example.  Or do you set the
GCONV_PATH environment variable on the affected system?

In my initial tests, the counter was stuck at 1 due to the gconv cache,
but that requires the gconv-modules.cache file being present at the
expected path, and GCONV_PATH must not be set.  In this case, you should
be able to work around this issue by running iconvconfig (or not setting
GCONV_PATH).

I cannot yet reproduce the crash, but I definitely see the counter
wrap-around.

Thanks,
Florian
