--- Comment #7 from Matt Hargett <matt at use dot net> 2012-05-11 20:19:01 UTC --- Applying the patch does allow DWARF serialization to get further, but now it dies here: internal compiler error: in add_AT_specification, at dwarf2out.c:7536 It looks like this problem (hiding beneath the original) is related to PR47839, whose fix was fortran front-end specific. Should I just file a new bug and reference these other bugs?
