Does anyone have a > quick idea for what may have caused the slow-down? It will be a change in the BFD library. More specifically it is likely to be a change to bfd/dwarf2.c. Have a look at the ChangeLog in the bfd/ directory for the 2.37 release for more hints. I suspect, but do not know for sure, that it could be the patch for PR 27484 .... Cheers Nick
