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. =)
The patch looks good, I've tested a build with it. Can be applied.
I'm going ahead and setting the maintainer-feedback+ on this one, given your response. Please do reset it if you wish and let me know if this is a problem. =)
