dmalloc (look in pkgsrc/devel/dmalloc) shows 26 lines like:

	1000452103: 113:  not freed: '0x8096208|s3' (160 bytes) from 'ra=0x480cf1c9'

when "find . -type f -exec ls \;" is run on a directory with 26 files :(
I haven't looked any further than this yet.

For now, it may be simpler to use xargs(1).  Maybe

	find . -type f -print | xargs crc-calc-program

or (if crc-calc-program can only handle one argument at a time)

	find . -type f -print | xargs -n 1 crc-calc-program

If crc-calc-program can indeed process more than one file at a time, the
first xargs form will result in a lot less fork/exec's and will be more
