printf and wprintf together with libc.so.6

[Arthur Prosso]

Hello,
I have the following problem:

If the first output command in the program  is printf , then any subsequent 
wprintf command 
produces an empty result - nothing is outputted at all (errno is 0, but return 
value is -1) .

If the first output command in the program is wprintf , then any subsequent 
printf command 
produces an empty result - nothing is outputted at all (errno is 0, but return 
value is -1) .

I use gcc-3.2.3 and libc.so.6 on Red Hat Linux  7.3

On Solaris 9 with gcc-2.95 and libc.so.1 the same piece of code works correctly.

Is it a bug of libc? 
Thank you in advance
