Re: PSPP-BUG: "ERROR I/O" on a large database on version 0.7.9 Win7 binary

[Gong, Henry]

Hi,

This problem seems to keep coming and going.  And it only has been reported on
Windows, and it seems only on some Windows machines which are configured in a
particular way (we don't know the exact criteria).

Maybe "SHOW ALL" gives some info. I would especially be interersted in the amount of free space on the tempdrive and the temporary file size generated.

Maybe there is an issue with the max file size of 2 GB

I've gone ahead and run SHOW ALL; here's the syntax.

SHOW ALL.

note: SHOW: BLANKS is SYSMIS.
note: SHOW: CCA is .
note: SHOW: CCB is .
note: SHOW: CCC is .
note: SHOW: CCD is .
note: SHOW: CCE is .
note: SHOW: DECIMALS is `.'.
note: SHOW: DIRECTORY is C:\Program Files\pspp\bin.
note: SHOW: ENVIRONMENT is x86_64-w64-mingw32.
note: SHOW: ERRORS is BOTH.
note: SHOW: FORMAT is F8.2.
note: SHOW: LENGTH is 25.
note: SHOW: LOCALE is CP1252.
note: SHOW: MESSAGES is BOTH.
note: SHOW: MXERRS is 100.
note: SHOW: MXLOOPS is 40.
note: SHOW: MXWARNS is 100.
note: SHOW: N is 51475.
note: SHOW: PRINTBACk is NONE.
note: SHOW: RESULTS is BOTH.
note: SHOW: RIB is LSBFIRST (NATIVE).
note: SHOW: RRB is IDL (64-bit IEEE 754 double, little-endian) (NATIVE).
note: SHOW: SCOMPRESSION is ON.
note: SHOW: TEMPDIR is C:\Users\User\AppData\Local\Temp/psppJnmXOk.
note: SHOW: UNDEFINED is WARN.
note: SHOW: VERSION is GNU pspp 0.7.9-gf863b6.
note: SHOW: WEIGHT is OFF.
note: SHOW: WIB is LSBFIRST (NATIVE).
note: SHOW: WRB is IDL (64-bit IEEE 754 double, little-endian) (NATIVE).
note: SHOW: WIDTH is 80.

And here is a list of temp file sizes (in MB):

56.3 x 3
63.3 x 18
65.3 x 2
80.9 x 1.

I'd like to help fix the bug; I should be able to run tests most weekdays.
