Update DR and fix associated DR and recent-Linux issues (#2484) Updates DR to bbd4ffadd. Fixes several issues with the latest DR and recent Linux platforms: + DWARF5 is now the gcc default but is not supported (#2485) so we add -gdwarf-4 to our test flags and the docs. + Adds Linux syscall entries for rseq and getrandom, seen on tiny apps now. + Fixes a bug in the size of kernel_sigset_t which was resulting in false positive uninitialized errors in rt_sigaction. + Updates drltrace code for droption now being in a namespace. + Adds --recursive to the git submodule commands to get minizip for the DR build. + Relaxes the drltrace tests to allow __IO_puts and __open.
Dr. Memory is a memory monitoring tool capable of identifying memory-related programming errors such as accesses of uninitialized memory, accesses to unaddressable memory (including outside of allocated heap units and heap underflow and overflow), accesses to freed memory, double frees, memory leaks, and (on Windows) handle leaks, GDI API usage errors, and accesses to un-reserved thread local storage slots.
Dr. Memory operates on unmodified application binaries running on Windows, Linux, Mac, or Android on commodity IA-32, AMD64, and ARM hardware.
Dr. Memory is released under an LGPL license and binary packages are available for download.
Dr. Memory is built on the DynamoRIO dynamic instrumentation tool plaform.
Dr. Memory is faster than comparable tools, including Valgrind, as shown in our CGO 2011 paper Practical Memory Checking with Dr. Memory, where we compare the two tools on Linux on the SPECCPU 2006 benchmark suite:
(Valgrind is unable to run 434.zeusmp and 447.dealII).
Documentation is included in the release package. We also maintain a copy for online browsing.
The Dr. Memory package includes an “strace for Windows” tool called drstrace.
Dr. Memory has its own discussion list.
