this issue was introduced by the changes in 151901. (I can obtain a successful bootstrap by reverting the changes of 151815, the dsymutil fail is then present, not present at 151900 with the changes of 151815 reverted). thanks for the pointer to possible libtool influence, however, the libtool-version listed in (e.g.) libgfortran claims not to have changed between 151000 and152000. > So in the end this is very likely still > a dsymutil bug - no user program should run into assertions anyway. agreed; however, at the moment I can't repeat this outside the GCC build process. running the command line (listed as failing in the log) manually on the freshly-built tree does not fail. "dwarfdump -av *.o" doesn't reveal any failures. if I build a lib by hand with the objects present and then run dsymutil on it - it doesn't fail. I'm also finding it difficult to check the dwarf-4 stuff since none of google, wiki or the gcc website are pointing to a DWARF4 spec to read. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41473
