Igor, All,

Thanks for your report.

However, you did not provide enough information. Can you provide:
  * the version of Buildroot you are using
  * the defconfig file your are using

I was also not able to reproduce with current master; the following ran
for quite some time, but trigerred not (related) issue:

    $ while ! ( grep -q -E '^BR2_PACKAGE_LIBICONV=y' .config \
             && grep -q -E '^BR2_ENABLE_LOCALE=y' .config)
    do
        make randconfig
    done

Regards,
Yann E. MORIN.
