Nope, environment makes no difference.

Finally found the time to track down the bug on my machine. It is
triggered by CONFIG_LOCALE_SUPPORT. Disabling that option makes the bug
go away reliably. (I also noticed this option is not enabled by default.)

Interestingly, whether CONFIG_UNICODE_SUPPORT is enabled or not does not
seem to make any difference.

So now I don't know if the bug is in busybox, in my local C library (GNU
glibc 2.17 on Slackware 14.1), or some combination of both.

Happy holidays,
