[sane-devel] [patch] scanimage leaks memory in batch mode

[Olaf Meeuwissen]

Hi all,

Just noticed that scanimage leaks buffer_size bytes per scan when used
in batch mode.  By default, that's 32 kb.  When using the buffer-size
option it's 1Mb or whatever size you passed.

Patch is attached.  It moves the memory allocation out of scan_it() and
into main(), just before where the non-test-mode branch starts the batch
loop.

Hope this helps,
