Has anyone else still been noticing difficult to reproduce memory

context of a large program. However, they don't occur in 2.040 (the
release
before the array stomping patch), and they are clearly a result of memory
corruption, as contents of arrays change from what I expect them to be to
completely random-looking values inside a loop that does a lot of memory
management and uses AAs heavily but doesn't modify the values.
I just thought of a way to rule out or not the stomping patch, as long as
your code does not depend on preventing array stomping.
Change your runtime's version of lifetime.d to the version before the
append stomping patch:
http://www.dsource.org/projects/druntime/browser/trunk/src/rt/lifetime.d?rev=251
This version should be forwards compatible with the runtime in 2.042, so
you should be able to run your code with this runtime. See if the errors
still occur.
