The following one-liner runs in an endless loop on 0.11.15.
node --harmony --use-strict -e 'for (let i = 0; i < 3; ++i) { if (i == 1) { continue; } }'

Replace 'let' with 'var' to avoid the bug.

Bug does not show up in 0.11.14.

Tested with a clean docker image, created like this:
FROM node:0.11.15
CMD node --harmony --use-strict -e 'for (let i = 0; i < 3; ++i) { if (i == 1) { continue; } }'
