find attached a simple program that will cause a segfault in fwrite()
the conditions to reproduce seem to be:
output size > 4096
input size > 4096
fopen a file with w+ mode
write a little
read a little (with a limit >4096)
write a lot (more than 4096)
if any of these steps are omitted, then the test case works fine
tested on debian/x86/unstable with glibc-2.3.2 (debian ver ds1.22) and
gentoo/amd64/unstable with glibc-2.3.5
gcc version did not seem to matter as diff versions of 3.3.x, 3.4.x and 4.0.x
all failed
