Description of problem: grep -Fw may find an incorrect match Version-Release number of selected component (if applicable): grep-2.5.1-31 How reproducible: Every time. Steps to Reproduce: Run grep -fW with 2 words to match, one which matches the end of a word and the other teh start of the same word. But neither matches a whole word (well, that seems to be the requirement). Actual results: grep reports a match: Expected results: grep should not report a match Additional info: A specific example for grep built from the source rpm, with all patches applied. my-system*[1] echo "LIN7C 55327" | ../grep-2.5.1a/src/grep -wF -e 5327 -e 5532 LIN7C 55327 This is grep-specific rather than FC3-specific. Compiling the same code on an Irix system produces the same error.
Confirmed with 2.5.1-31.4. This works fine in 2.5.1-48 from rawhide (Fedora Core development).
