What steps will reproduce the problem? 1. ./drmemory -show_reachable -- /usr/local/src/mcu/bin/debug/mcu What is the expected output? What do you see instead? <Application /usr/local/src/mcu/bin/debug/mcu (8979). Platform exception at PC 0xb7658d25. Please report this. Program aborted.

On what operating system? root@ubuntu:~/DrMemory-Linux-1.7.0-5/bin# ./drmemory -version Dr. Memory version 1.7.0 -- build 5

Does the problem go away when running in light mode (pass "-light" to Dr. Memory)? What about when running with the options "-leaks_only -no_count_leaks -no_track_allocs"? -ligth same behaviour -leaks_only -no_count_leaks -no_track_allocs doesn't exit inmediatelly but after pressing ctrl-c got same behaviour Does the problem go away when using the most recent build from http://build.chromium.org/p/client.drmemory/builds/? no, version 1948 has same behaviour Try the debug version of Dr. Memory and of its underlying engine DynamoRIO by passing "-debug -dr_debug -pause_at_assert" to drmemory.exe.

Can you point us to where we can find this mcu program so we can try to reproduce?
