dtrace discuss - Oct 2008 - Difference between dtrace 1.1 and 1.3

Hi all;

The following script works well with dtrace 1.1 but return the following 
error with dtrace 1.3

dtrace: failed to compile script log-memory.d: line 3: probe description 
pid25659:libc:malloc:entry does not match any probes

Thanks for any suggestion.

#!/usr/sbin/dtrace -s

pid$1:libc:malloc:
entry{
        self->trace = 1;        self->size = arg0;
}

pid$1:libc:malloc:return
/self->trace == 1 && self->size > $2/
{
        printf("Ptr=0x%p Size=%d TS=%d AllocTime=%Y", arg1,
self->size,
timestamp, walltimestamp);
        ustack();
        self->trace = 0;
        self->size = 0;
    allocated[arg1] = 1;
}

Hey Benoit,

Can you send me (in private mail) the output of your command adding -x  
debug? Also, have you tried fully specifying the library as libc.so.1?  
Thanks.
