Bug ID: 60315 Summary: template constructor switch optimization Product: gcc Version: unknown Status: UNCONFIRMED Severity: minor Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: garcia.espinosa.jr at gmail dot com Created attachment 32198 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32198&action=edit code to trigger the error when compiled with "gcc -O1 test.cpp" g++ 4.8 huge (infinite?) compiling time when optimization is requested (any -Ox) Code works well with previous versions (4.6, 4.7), or if no optimization is requested. Also, if the number of switch cases is reduced to 3 (eg comment out the case E4 line), no noticeable compiling time Tested: GCC 4.8.1, Linux x86_64 (ubuntu 12.04 and others)
