Hi All,
With recent updates to hwasan runtime libraries, the error reporting for
this particular check is has been reworked.
I would question why it has lost this message. To me it looks strange
that num_descriptions_printed is incremented whenever we call
PrintHeapOrGlobalCandidate whether that function prints anything or not.
(See PrintAddressDescription in libsanitizer/hwasan/hwasan_report.cpp).
The message is no longer printed because we increment this
num_descriptions_printed variable indicating that we have found some
description.
I would like to question this upstream, but it doesn't look that much of
a problem and if pressed for time we should just change our testsuite.
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Ok for master?
Thanks,
Tamar
