yes, one of the things that --stats=yes activates is some information
about laog GC.

helgrind data structures are different of drd (a.o. to be able
to give precise information about race conditios).
Normally, --stats=yes should have produced statistics
at the end of your program (if your program exited due to
out of memory). If valgrind itself encountered the oom situation
then it should equally have produced statistics.
Can you post here these statistics ?
If they are not produced (unclear why), then you could instead
regularly run in another window
vgdb -c v.info stats -c v.info memory
to capture stats/memory during the run, before it reaches 64G.
