sorry didn't look at what you were referencing in my mail. the problem was XFS not marking some blocks added to a file as new, causing extraneous garbage to show up at the end of a file, but only if you read the file via mmap() (gcc 3.1 does this, and thus reports syntax and other errors in lines which apparently do not exist. any program which uses mmap on files will malfunction). there is a utility to check for files with this problem and repair them, i made a couple minor enhancments and bugfixes to it: http://penguinppc.org/~eb/files/mapcheck.c to scan but not repair run mapcheck -n -v -a to repair remove the -n switch. the bug first appeared in later 2.4.18 CVS snapshots, and was fixed there a couple weeks later, it reappeared sometimes in the 2.4.19-pre stages in XFS CVS (definitly including -rc2 through final 2.4.19 split patches) its currently fixed in CVS, or i have the standalone patch against 2.4.19+split patches if your like my and prefer to stay at known snapshots. -- Ethan Benson http://www.alaska.net/~erbenson/
