stackbase2 is being zeroed with no memory allocated for it.
That's probably your problem.
<EDIT>
Nevermind. I don't understand the gymnastics you are doing with the stackbase and size parameters to test_main.
You are passing what looks like an invalid address with the the pointer arithmetic here:
Code:
base+PTHREAD_STACK_MIN
and then attempting to set the stack to this address. That's all I can see.

I am currently using SIGUSR1 and SIGUSR2 - but I need another one.
How can I do that?

Hi;
Is der ne to to use user defined functions for the values in awk
find $1 -type f -ls | nawk '{{print "|"$3"|"$5"|"$6"|"$8"|"$9"|"$10"|"} for(i=11;i<=NF;i++){printf("%s",$i)}}'
In above command i want to append some values returned by user functions on line.
thnks;

stack_shrink
STACK(9) BSD Kernel Developer's Manual STACK(9)NAME
STACK -- stack macros
SYNOPSIS
#include <sys/param.h>
type
STACK_ALLOC(sp, size);
type
STACK_MAX(sp, size);
type
STACK_ALIGN(sp, bytes);
type
STACK_GROW(sp, size);
type
STACK_SHRINK(sp, size);
DESCRIPTION
A stack is an area of memory with a fixed origin but with a variable size. A stack pointer points to the most recently referenced location
on the stack. Initially, when the stack has a size of zero, the stack pointer points to the origin of the stack. When data items are added
to the stack, the stack pointer moves away from the origin.
The STACK_ALLOC() macro returns a pointer to allocated stack space of some size. Given the returned pointer sp and size, STACK_MAX() returns
the maximum stack address of the allocated stack space. The STACK_ALIGN() macro can be used to align the stack pointer sp by the specified
amount of bytes.
Two basic operations are common to all stacks: a data item is added (``push'') to the location pointed by sp or a data item is removed
(``pop'') from the stack. The stack pointer must be subsequently adjusted by the size of the data item. The STACK_GROW() and STACK_SHRINK()
macros adjust the stack pointer sp by given size.
A stack may grow either up or down. The described macros take this into account by using the __MACHINE_STACK_GROWS_UP preprocessor define.
