#1037 closed defect (fixed)

byte-blob-find fails on certain matches on 32-bit Chicken

Reported by: dthedens Owned by: Ivan Raikov
Priority: major Milestone: someday
Component: extensions Version: 4.7.x
Keywords: byte-blob, 32-bit Cc:
Estimated difficulty:


(byte-blob-find (list->byte-blob (list 1 31)) (list->byte-blob (list 0 1 31 3)))

fails to match on 32-bit, but succeeds on 64-bit. Replace 31 with any byte value with low 5 bits all set (63, 95, etc.) and matches also fail. This may be related to the fact that internal function (swizzle 31) -> 0 on 32-bit, but is #x80000000 on 64-bit.

Hello, thanks for the bug report. I have rewritten swizzle so that it does not rely on 64-bit integers, and I have made a new release of byte-blob. Please try it out and let me know if it works for you.

Yes, this seems to have fixed my small test case as well as my original problem on 32 bit. Thanks for the quick turnaround!
