bad-free error when building with memory sanitizer flag

[JEGroeneweg]

Hi,

In our project we are linking to your library, unfortunately we came across a problem. Whenever we are building our project with a sanitizer flag we encounter a runtime error. If I build Ifopt with the same flag the error disappears.

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -fsanitize=address -fno-omit-frame-pointer -O0")

I've added one of the Ifopt tests to our project, to see if the same error would appear (it does). The test that I copied is the problem_test.cc from the core folder. The test which gives problems is the GetVariableValues test, the problem particular seems to occur in the ifopt::Composite::GetValues() functionality, which corresponds to what we find in our own project.

Is there someone who can take a look where this behavior is coming from?
