Re: [RFC] Quad-float support in Fortran

Hmm, that does not tell much - seemingly, libqfortran/libquad is
compiled without debugging symbols.

Actually, if you compile your program statically, it indeed might be a
problem with weak ref. Can you compile your program using:

gfortran -Wl,--whole-archive -lquadmath -Wl,--no-whole-archive test.f90

This works just fine:

$ gfortran-4.6 -Wl,--whole-archive -lquadmath -Wl,--no-whole-archive test_qp.f90 -o test_qp-new

$ ./test_qp-new

or completely static:

gfortran -static \
-Wl,--whole-archive \
-lpthread -lquadmath \
-Wl,--no-whole-archive test.f90

Also this:

$ gfortran-4.6 -static -Wl,--whole-archive -lpthread -lquadmath -Wl,--no-whole-archive test_qp.f90 -o test_qp-new

$ ./test_qp-new
