Thanks All In fact, to answer Pete, I was trying to do as much as possible like valgrind including as much as possible, which includes all tools. M very elated to know about ASan, given the fact that LLVM is Compile time whereas valgrind is Dynamic, need to rethink, Can you guys check this. build clang 3.2 but I got this linker error. Let me also examine closely clang++ -W -Wall

Did you checkout compiler-rt? This page has detailed info on building asan: http://code.google.com/p/address-sanitizer/wiki/HowToBuild?tm=4 --kcc On Mon, Jan 7, 2013 at 9:38 PM, Devchandra L Meetei <dlmeetei at gmail.com>wrote: > Thanks All > In fact, to answer Pete, I was trying to do as much as possible like > valgrind including as much as possible, which includes all tools.

Turns out compiler-rt was missing as pointed out by Kostya. Any clue why line number is not printed, It got compiled with -g -O1 along with flags specified in the link I got following lines on RHEL 6.3 clang 3.2 ==10474== ERROR: AddressSanitizer: heap-use-after-free on address 0x7fb3eb2c6b90 at pc 0x415394 bp 0x7fff49175eb0 sp 0x7fff49175ea8 READ of size 4 at 0x7fb3eb2c6b90 thread T0 #0
