In EREs, left-brace is not to be interpreted as an ordinary character unless escaped. Using left-brace not as a part of a valid interval expression produces undefined results .
There is a patch-in-progress to fix our implementation to throw an error if left-brace is not used in a valid manner, it would be good to go ahead and address this before-hand. =)
Looking good, patch works fine and build works. Thanks for finding and providing the patch.
