Bug #: 56109
Summary: Add light-weight ABI-compatible debug checks to
standard containers
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ppluzhni...@google.com
Google has implemented a series of patches which allows us to catch many STL
mis-use bugs cheaply and in ABI-compatible way:
http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01186.html
http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01074.html and more ...
(just look for __google_stl in google/integration branch).
Some of the bugs we catch this way are not visible to "standard" tools like
Valgrind and AddressSanitizer.
These bugs (and more) *are* visible to _GLIBCXX_DEBUG mode, but we've not been
able to use that mode due to source incompatibilities, and it has ABI
implications as well.
Please consider adding a light-weight ABI-compatible debug mode to trunk, once
it re-opens for stage 1.
