Dear HJ, I can confirm that the part of resolve.c modified in r220191 is not visited by the compilation of class_allocate_18.f90. If I have understood correctly, -fPIC is not supported on x86_64 and so, unless I am mistaken, I cannot help you further. Please let me know if there is anything that I can do to help.
