Hi all,
I ported linux to my embeded board and encountered a
weird "printf" problem.
The library i used is uClibc.
I made the kernel to run a testing program directly after boot
up.
In my case, less "printf" work well but more will
fail.
Here is my testing program:
main()
{
int i=0;
while(i<200)
{ printf("Hello World=%d\n",i); i++; } }
The output message will die at "Hello World=10" or "Hello
World=168" or "Hello World=76" ........
Every times the message dies at different place but it will never successfully be outputed "200"
times.
However, if the condition is changed to "while(i<100)",
then everything is fine.
It is so weird!!
Why too much "printf" will cause the program to
die?
Is it the problem of uClibc or kernel?
Does the compiler for my testing program concern this weird problem?
Can anybody give me some hints?
Thanks,
