address-sanitizer

Installing MinGW-w64 5.1 I find -fsanitize=address is available. It compiles fine, and when it starts linking I get thousands of: undefined reference to '__asan_report_load1' undefined reference to '__asan_report_load4' I googled and found libasan referenced various places, but also comments that when you include -fsanitize=address it automatically includes that library for linking. I searched the MinGW-w64 5.1 install dirctory for "asan" and it was not found anywhere. What do I need to add on to use address sanitizing features in MinGW-w64? Thank you. I've looked quickly into release notes

I just tried compiling with GCC and the -fsanitize=address flag. When I run my program, the address sanitizer finds a flaw, but the stack trace is not helpful. How can I configure this so that it points to the source code locations I need to look at? ================================================================= ==32415== ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6006004b38a0 at pc 0x10b136d5c bp 0x7fff54b8e5d0 sp 0x7fff54b8e5c8 WRITE of size 8 at 0x6006004b38a0 thread T0 #0 0x10b136d5b (/Users/cls/workspace/NetworKit/./NetworKit-Tests-D+0x1000c6d5b) #1 0x10b136e0c (/Users

I'm trying to build my project with g++ -O0 -g -fsanitize=address -fno-omit-frame-pointer but get lots of errors like: /home/user/libs/opencv/include/opencv2/core/mat.hpp:715: undefined reference to `__asan_report_load8' How to compile project with AddressSanitize support? My gcc version is 4.8.4. You need to add the switch -lasan to your compile/link command line to link the correct library. You need to add -fsanitize=address to both compiler flags ( CFLAGS , CXXFLAGS ) and linker flags ( LDFLAGS ). You've probably added it to your compiler flags only. Note that using explicit -lasan option
