st: Stata 12 MP rounds off large double value on read

Dear Stata gurus,
I am trying to read a plain-text tab-delimited file from disk into Stata with the *insheet* command. There are three lines in the file that cause me trouble, and their values are:
9223372034619058931
9223372034619059031
9223372034619058731
The *insheet* command converts these to *double* storage type, and rounds each of these values to the same number: 9223372034619059200. I am puzzled as to what may be the underlying issue. Moreover, when I try to issue the following command:
generate double x = 9223372034619058931
I get the variable *x* with all values being equal to 9223372034619059200, again.
I have found a workaround by forcing Stata to read these numbers in as strings. But I would like to try to avoid this because of storage inefficiencies.
Does anyone have any ideas what may be causing this behavior?
Thank you,
