As it is visible, addr2line is not able to display proper information for the
__libc_start_main function despite of this information is available within DEBUG
info from the binary.
Also, looking at the internal BFD structures built from the binary, I've found
the the symbol element for this function is probably inconsistent. It's name
attribute contains "__libc_start_main@@GLIBC_2.0" and the
bfd_get_section_vma(abfd, symbol->section); returns zero as the starting address
for the section which this symbol belongs to. This could be a possible cause of
the problem
