To reproduce it:

# git clone git://git.busybox.net/buildroot
# wget https://git.busybox.net/buildroot-test/tree/utils/br-reproduce-build

- modify BASE_GIT=... with your buildroot path in br-reproduce-build then:
# chmod a+x br-reproduce-build
# ./br-reproduce-build a05fdf1958f93a206c5c66c7f636b6650683626d

I've not found a work around for this bug.
