Hi,
during a valgrind debug session with a small parallel program I noticed this
message from valgrid:
==13513== Source and destination overlap in memcpy(0x435feebc, 0x435feebc, 8)
==13513== at 0x40025BD5: memcpy (mac_replace_strmem.c:95)
==13513== by 0x82716E4: lam_memcpy (in
/home/tems/concept.f90/be/pconcept.be)
I am using a self compiled version of LAM, configured with these options:
./configure --prefix=/opt/intel/compiler70/lam \
--with-prefix-memcpy \
--with-purify \
--with-trillium \
--with-rsh=rsh \
--with-tm=/opt/pbs
As you see LAM uses the prefix-memcpy-feature as well as the purify feature
for usage of LAM together with valgrind. Does this message point to a
possible bug or is it a wanted behavior?
Regards,
Michael
