--- Comment #1 from Jan Beulich <jbeulich at suse dot com> --- (In reply to Jens Remus from comment #0) > A) Add an .eh_frame section size test to the if-condition, so that the > FDE start field is not filled in when the FDE got discarded. If such a check would be just checking for size being (non-)zero, that would be my preference here. It's not clear to me though if a discarded FDE would mean size to end up being zero, as a CIE might still be there. > B) Test rawsize instead of size in the assertion (assuming rawsize > corresponds to the contents buffer size). Note that rawsize > sometimes is zero, although size is set and the contents buffer is > initialized. Therefore rawsize would need to be initialized as well. Given what you say, this doesn't look to be a viable option. Then again _bfd_elf_write_section_eh_frame() simply sets ->rawsize from ->size when still zero. > C) Ignore and do not add any assertion(s), as the subject .eh_frame > sections are linker generated and thus the contents buffer should > always have enough room (assuming the linker never reallocates the > contents buffer when discarding the FDE). This might be a last resort. For a fully squashed section I wonder though whether ->contents wouldn't then better also be cleared, in which case the existing conditionals would already cover the case. Anyway - curious what H.J.'s take is here. -- You are receiving this mail because: You are on the CC list for the bug.
