Hi Mark

thanks for your input.

Didn't work though :(

I've put a bit of debug messages to see where it is passing and it always pass in the "compr" check:

pad = size % TAR_BLOCKSIZE ? (TAR_BLOCKSIZE - (size % TAR_BLOCKSIZE)) : 0;
if (compr) {
if (off == gzseek(dbio->gzs, 0, SEEK_CUR)) {
gzsek = gzseek(dbio->gzs, (long)size + pad, SEEK_CUR);
printf("gzseek \n");
}
else if (pad) {
gzseek(dbio->gzs, pad, SEEK_CUR);
printf("pad gzseek \n");
}

Now the loop says:

LibClamAV debug: cli_tgzload: Loading COPYING, size: 17992

gzseek
LibClamAV debug: cli_tgzload: Loading COPYING, size: 17992
gzseek

so it's in the first part of the "if".

Thinking it could have been a problem with gzseek I've added the "gzsek" variable so I can check the return value:

if ( gzsek == -1 )
break;

but it stays in loop.

So it could eventually be a problem with the libz library ....

I've filed a bug to bugzilla, but try to find also by myself.
