PID provider can not create memcpy:return probe for 64bit process
...return
dtrace: invalid probe specifier pid10603:libc.so.1:memcpy:return:
probe description pid10603:libc.so.1:memcpy:return does not match any probes
This just happens for 64bit process, 32bit process has no such a issue.
Following is dtrace output for 32bit-process
# dtrace -n pid403:libc.so.1:memcpy:return
dtrace: description ''pid403:libc.so.1:memcpy:return'' matched 1 probe
^C
Disable shows that 64bit memcpy function has many branches for ret
instructions:
# mdb -p 10603
