Description du projet

Memcheck provides the ability to fault on pointer

overrun (read or write) or freed pointer

deference (read or write), logs double free and realloc of already freed pointers and memory not freed on exit, checks for pointer underrun on free and realloc, optionally reverses the behavior of overrun and underrun, "churns" reallocations to always return a different pointer, and logs pointer overruns instead of faulting. It has a very small performance impact, with the tradeoff of a large memory footprint. It includes a validation test suite to verify correctness of the library. It is tested on a variety of architectures, including Alpha, ARM, HPPA, PPC, ix86, IA64, rs6000, S390, SPARC, and SPARC64. It is tested on a variety of platforms, including OSF, FreeBSD, NetBSD, OpenBSD, Linux, HP/UX, Mac OSX, AIX, SCO, and Solaris.

0.1.2

Deux nouvelles fonctionnalités facultatives sont maintenant disponibles: l'enregistrement des «grands» les allocations et les exécute délibérément hors de la mémoire. Stacktraces sont désormais pris en charge sur les systèmes avec glibc. Le montant de l'exploitation forestière peut maintenant être contrôlée. La plupart des plates-formes déjà partiellement pris en charge sont maintenant complètement supportés. Nouvelles plates-formes pris en charge incluent i386-pc-sco3.2v5.0.4, s390-ibm-linux-gnu, sparc-unknown-netbsdelf1.5, et x86_64-pc-linux-gnu. La configuration est désormais fait avec une seule variable Vérification mémoire environnement.
Tags: Minor feature enhancements, Stable
Two new optional features are now available: logging of "large" allocations and deliberately running out-of-memory. Stacktraces are now supported on systems with glibc. The amount of logging can now be controlled. Most of the previously partially-supported platforms are now completely supported. New platforms supported include i386-pc-sco3.2v5.0.4, s390-ibm-linux-gnu, sparc-unknown-netbsdelf1.5, and x86_64-unknown-linux-gnu. Configuration is now done with a single MEMCHECK environment variable.
