--- Comment #15 from Evgeniy Stepanov <eugeni.stepanov at gmail dot com> ---
In fact, a recent change disabled ASAN_FLEXIBLE_MAPPING_AND_OFFSET and killed
all supporting code. Or are you talking about a different change?
ASAN_FLEXIBLE_MAPPING_AND_OFFSET indeed prevents LD_PRELOAD with unsanitized
binaries, and it was one of the reasons for killing it.
