BC2 hang when compare corrupted .tar.gz

Using BC 2.5.1. When BC2 compare a corrupted .tar.gz (CRC failed), BC2 will hang forever.

BC2 hang when try to compare a perfect .tar.gz with a partially downloaded .tar.gz (naturally will have CRC failed).

Not sure what will happen to BC2 with the same situation using .zip files.

Hi Frank,

If the files causing the problem are small enough to send by email, please send an example to support@scootersoftware.com and we'll take a look into this issue.

Sorry, I am not able to send out any email with corrupted .tar.gz. The SMTP Anti-Virus protection is very smart to reject such files, including encrypted zip.

So here are the steps to recreate.
1. Download http://internap.dl.sourceforge.net/sourceforge/mingw/mingw32-make-3.81-2.tar.gz (97305 bytes)

2. Copy the perfect mingw32-make-3.81-2.tar.gz to mingw32-make-3.81-2-CRC.tar.gz

3. Simulate partial download by using Hex-Editor to cut the tail end of mingw32-make-3.81-2-CRC.tar.gz to 78192 bytes.

4. Compare mingw32-make-3.81-2.tar.gz and mingw32-make-3.81-2-CRC.tar.gz. It will hang and keep consume disk space.

MD5SUM of the two .tar.gz
ed5388ab407f56dcac636040bcf57dc5 *mingw32-make-3.81-2-CRC.tar.gz

Frank,

Thanks for the detailed description of the problem. I duplicated the error on my own computer. I'll pass this on to our developers and we'll work on a fix.
