Hi,
I wonder if it's possible to generate cores (or rather vgcores) when
valgrind detects invalid reads or writes. We do occasionally see such
reports by valgrind, and it would be really helpful to be able to
investigate the internal state using gdb. But I don't see any such
option in valgrind :-(
I was thinking about triggering a segfault somehow, but the trouble is I
don't really know how to identify that the read actually was invalid
(which is a very rare event).
Adding more detailed logging is another possibility, but it's going to
be very tedious to identify traces matching the invalid access.
Is there a way to get core when valgrind on invalid access? Am I missing
something?
regards
Tomas
