Hi,
I have come across with char Limit issue on 2.6.29 kernels.
SIGFAULT:
#define SIZE 8053759
char buf1[SIZE] ;
NO SIGFAULT:
#define SIZE 8053758
char buf1[SIZE] ;
This SIGFAULT not observed on 2.6.23 kernels.
What could be the changes that effecting from 2.6.23 to 2.6.29 kernels.
Please share me the information.
Best regards,
Naresh Kamboju

Some more feedback...
It's SEGFAULT - short for "Segmentation Fault", not SIGFAULT.
Please include in your details at least the following:
* what software this is in (is this declaration in the kernel?, a library, a
user space program, etc.)
* what operation is being performed when the SEGFAULT occurs.
* what compiler you are using.
* the code surrounding the operation when the fault occurs
If you can, make the smallest possible program that reproduces this error,
and send the complete source for that.

is "ulimit -a" the same on both kernels?
Can you provide a small program that shows the issue?
