I tried both my system libtiff (3.9.4 too but on slackware) and the CVS head of 4.0 and got a segfault in jpeg_read_raw_data. This seems to be called from libtiff just after the code which generates the error you got above so it's probably related.
The behaviour is consistent across a couple different versions of Fedora- built and personally-build libtiffs. there some special libtiff Is

I suspect the different results we're seeing between people here might have something to do with the libjpeg involved. Mine is libjpeg.so.8.0.1. Oh and for what it's worth, I get the segfault no matter how large I make the buffer in your test program.
