Don't know if it's the same bug, but seems to be very similar.
There is a workaround that involves patching tzdata package (comment #6), which helped in that case with Russian timezones, and maybe will do for you. But I really think that fixing glibc is a correct way to resolve the problem, as it significantly affects performance under some workloads.
Also there is some technical info mentioned in comment #4 that may help in resolving this bug.
