Can you recognize this code:

template <class bar> struct foo { void fuz(); ~foo(); };
struct baz { int i; foo<baz> j; } *p = 0;
template <class bar> void foo<bar>::fuz() { delete p; }
template <class bar> foo<bar>::~foo() { delete p; }
template class foo<baz>;
int main() { foo<baz>(); }

Believe me, it is a simplification of your testcase, that I'm
installing in the testsuite.  IMO, it gives a new meaning to the
military expression `fubar' :-)

Thanks for your report.

I couldn't reproduce this problem; are you sure it doesn't have
anything to do with a wrong library path?
