             Bug #: 14626
           Summary: The systemtap failed to catch the user_process $$parms
                    and variety in Ubuntu 12.10 Beta
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dyninst
        AssignedTo: systemtap@sourceware.org

Platform:
Linux ubuntu 3.5.0-13-generic #14-Ubuntu SMP Wed Aug 29 16:48:44 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux

Systemtap:
Systemtap translator/driver (version 2.0/0.153, commit
release-1.8-244-gec12f84)

Descript:
I compile the systemtapãfrom git source. Everything works well except catch the
$$parms and variety in user_proccess.

Source:
#include <iostream>
int func(int i, int j)
{
    std::cout<<i<<std::endl;
    return i;
}
int main()
{
    func(3, 5);
    func(1, 2);
    return 0;
}

Command:
sudo stap -d /lib/x86_64-linux-gnu/libc-2.15.so  -ve 'probe
process("a.out").function("func") {log($$parms); printf("i = %ld and j =
%ld\n",$i, $j)}'

Expectãoutput:
i=3 j=5
i = 3 and j = 5
i=1 j=2
i = 1 and j = 2

Output:
i=0x0 j=0x400700
i = 0 and j = 4196096
i=0x3 j=0x5
i = 3 and j = 5
