--- Comment #24 from Mathieu Malaterre <malat at debian dot org> ---
I have change the openvdb.cc code into:

% cat openvdb.cc
#include "Tree.h"

static std::string do_segfault() { return Tree::treeType(); }

#ifdef VIS
__attribute__((visibility("default")))
#endif
void initialize()
{
  do_segfault();
}

Now I can demonstrate that the issue only happen when using the visibility flag
(no-symptom using the default UNIX mechanism to export all symbols).
