It appears that in the Layout::sized_create_version_sections function the first
thing is does is:
Output_section* vsec = this->choose_output_section(NULL, ".gnu.version",
elfcpp::SHT_GNU_versym,
elfcpp::SHF_ALLOC,
false);
which can return NULL, then a few lines down it does:
vsec->add_output_section_data(vdata);
which fails because vsec is NULL.
Upgrading to snapshot from 20091102 I now get the error:
internal error in address, at output.h:126
This doesn't trap in gdb, please let me know what extra information you need.
