Research direction
Start by reproducing the reported R call, DT[, Month := as.IDate(Month, format = "%Y-%m-%d")], and compare its behavior with data.table 1.10.4-3 and the newer version mentioned. The issue is resolved when this conversion completes without freezing; no source file or test is named in the report.

Description
@mattdowle, this time I'm using an issue and not twitter :)
The most recent version of data.table (built 11-23, IIRC) is freezing once again at IDate conversion. The call is:
DT[, Month := as.IDate(Month, format = "%Y-%m-%d")]
I'm sorry I don't have session info and traces but I had to downgrade to 1.10.4-3 to get the script to run and I'm up against a time limit. Then again, what happens is that it freezes at the conversion and just doesn't proceed.
