fdopen getc problem

[Matthias Braun]

Hi,

I try to compile ftptool 4.6p1 with gcc 2.95.3 and glibc 2.2.3.
I have the following behaviour.
In the coding a FILE is cretaed with responsefp = fdopen(s, "r"); It is a 
TCP socket to the ftp server.
In the function getreply the following code exists:

while ((c = getc(responsefp)) != '\n') {
...
}

The effect is now, that if I try to download multiple files and this code 
is reached for the seconde file, the fgetc give an EOF and the download is 
canceld.
The amazing thing is now, if I place a sleep(1); In front of this 
while/getc everthing works fine.

So my question is know, is this a bug or feature, that the getc gives an 
EOF if I read to quick from the opened socket stream?

Any ideas?
Matthias

PS: If I compile the same code under an old libc5 system I do not have this 
effect.
