Comment (by anonymous):

 Please raise the severity of this bug, I have encountered it as well.

 The fallout from this is that tz_database is completely broken on linux,
 causing your application to crash, this is a very serious bug.

 The explanation above is 100% accurate, boost::lexical_cast is being
 called with an extra '\r' on lines which need DST adjustments.

 Here is a GDB snapshot from my application:
