Summary: segfault in canonicalize_for_substitution
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: matz@gcc.gnu.org
Created attachment 24062
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24062
testcase
The patch for PR48207 broke compiling any moderately complex C++ program with
-g -flto. We can't use the C++ specific langhook for mangling when we've
already cleared out language specific stuff in free_lang_data.
$ cc1plus -g -flto bug.ii
