bfd_abs_section_ptr is created in bfd/section.c. Have a look for the
STD_SECTION macro. If this macro is failing to initialise the
output_section field of asection structure then there is a probably a
bug somewhere in your conversion of 32bit code to 64bit, so that it is
actually setting an earlier field in the structure (because it was
using a 32-bit field instead of a 64-bit wide field).
I would suggest running the program inside a debugger and then when
the seg fault occurs, printing out the entire contents of the
bfd_abs_section_ptr structure. Have a look at the fields and try to
work out where the mis-initialisation occurs.
