Caslyn Tonelli	f2a1726d21	[gwp_asan] Employ EXPECT_DEATH for zxtest compatibility ... Employ a similar tactic introduced by https://reviews.llvm.org/D94362 for gwp_asan tests. zxtest `ASSERT_DEATH` syntax differs from gtest in that it expects a lambda. zxtest does not have `EXPECT_DEATH`, so it introduced for Fuchsia builds and wraps the expression with a lambda to create a compatible syntax between zxtest and gtest for death tests. An example of where this compatiblity is needed is in `never_allocated.cpp`. Differential Revision: https://reviews.llvm.org/D147189	2023-04-18 21:57:30 +00:00
Mitch Phillips	bc949f923e	[GWP-ASan] Handle wild touches of the guarded pool. ... AllocMeta could be null when returned from __gwp_asan_get_metadata() for a bad access into the GuardedPagePool that was never allocated. Currently, then we dereference the null pointer, oops. Hoist the check up and print a message (only once in recoverable mode) about the bad memory access.
