Bug ID: 59868
Summary: Extremely slow compile times
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mikesart at gmail dot com
Building attached file takes ~20 minutes with gcc 4.8.1. Clang 3.3 builds in
~17 seconds. I'm happy to provide the blah.ii and blah.s files from the below
command as well, but it bumped the zip file size over 1MB so I've skipped them
for now. Please let me know if there is any other information I can provide.
Thanks.
