ASan allocator stores the requested alignment for new and new[] calls
and on delete and delete[] verifies that alignments do match.
The representable alignments are: default alignment, 8, 16, 32, 64, 128,
256 and 512 bytes. Alignments > 512 are stored as 512, hence two
different alignments > 512 will pass the check (possibly masking the bug),
but limited memory requirements deemed to be a resonable tradeoff for
relaxed conditions.
The feature is controlled by new_delete_type_mismatch flag, the same one
protecting new/delete matching size check.

Summary:
They might not be mapped on some platforms such as Win64. In
particular, this happens if the user address is null. There will not be
any shadow memory 5*16 bytes before the user address. This happens on
Win64 in the error_report_callback.cc test case. It's not clear why this
isn't a problem on Linux as well.

parameters. NFC.
Summary:
This is the first in a series of patches to refactor sanitizer_procmaps
to allow MachO section information to be exposed on darwin.
In addition, grouping all segment information in a single struct is
cleaner than passing it through a large set of output parameters, and
avoids the need for annotations of NULL parameters for unneeded
information.
The filename string is optional and must be managed and supplied by the
calling function. This is to allow the MemoryMappedSegment struct to be
stored on the stack without causing overly large stack sizes.

This patch prints out all CPU registers after a SIGSEGV. These are available in the signal handler context. Only implemented for Darwin. Can be turned off with the dump_registers flag.

Summary:
Finish work on PR30351 (last one, after D24551, D24552, and D24554 land)
Also replace the old ReportData structure/variable with the current_error_ static
member of the ScopedInErrorReport class.
This has the following side-effects:
- Move ASAN_ON_ERROR(); call to the start of the destructor, instead
of in StartReporting().
- We only generate the error structure after the
ScopedInErrorReport constructor finishes, so we can't call
ASAN_ON_ERROR() during the constructor. I think this makes more
sense, since we end up never running two of the ASAN_ON_ERROR()
callback. This also works the same way as error reporting, since
we end up having a lock around it. Otherwise we could end up
with the ASAN_ON_ERROR() call for error 1, then the
ASAN_ON_ERROR() call for error 2, and then lock the mutex for
reporting error 1.
- The __asan_get_report_* functions will be able to, in the future,
provide information about other errors that aren't a "generic
error". But we might want to rethink that API, since it's too
restricted. Ideally we teach lldb about the current_error_ member of
ScopedInErrorReport.

Summary:
@kcc: I know you've accepted the other revision, but since this is a
non-trivial change, I'm updating it to show why D24029 would help.
This commit sets up the infrastructure to use reified error
descriptions, and moves ReportStackOverflow to the new system.
After we convert all the errors, we'll be able to simplify ScopedInErrorReport
and remove the older debugging mechanism which had some errors partly reified
in some way. We'll be able to maintain the external API.
ScopedInErrorReport will be able to track one of the reified errors at a time.
The purpose of this is so we have its destructor actually print the error and
possibly interface with the debugger (will depend on the platform, of course).
