--- Comment #3 from Mark Wielaard <mark at gcc dot gnu.org> --- (In reply to Ian Lance Taylor from comment #2) > It looks like this would mean that libbacktrace needs an lzma decompressor. > This is probably doable but is probably non-trivial. At least it doesn't > look quite as bad as the zlib decompressor that we already have. Yes, it is basically an ELF image, containing just a symbol table, compressed with lzma inside an ELF section.
