Hi,all

I used a "-h" option from WAV and encoded it. A CRC error occurs if i do
verify of WV which made. But, as for the file which I encoded in "normal" from
same WAV, a CRC error does not occur. A check of MD5 tried it with possible
FLAC 1.2.1, but there was not a problem.

Same phenomenon is caused with both 4.41.0 and 4.50.0, but may cause a
problem by a tool outputting WAV from CD-DA?

*result of verify(foobar2000 v0.9.4.5+foo_verifier.dll)
Item: "D:\h_option.wv"
Error: CRC mismatch
Error: CRC mismatch
Error: CRC mismatch
Error: MD5 mismatch

Item: "D:\non_option.wv"
No problems found.

Item: "D:\preset_5.flac"
No problems found.


1 item could not be decoded.

List of undecodable items:
"D:\h_option.wv"

This sounds like you may possibly have a memory chip or CPU problem with the particular PC you are using. If both fast and normal compress ok (no errors when verifying) it sounds like the extra resources required to compress using -h is causing enough stress on your PC to result in these errors.
On one of my PCs I can compress using -h fine, but a more stressful compression like
wavpack -hb256x4cmy file.wav
causes a failure.

Best thing I can suggest is try to find a PC memory check utility and run it overnight and see if it shows any errors, then try a CPU checker if the memory test gives no errors.
