Bug ID: 64106 Summary: [5 Regression][C++14] internal compiler error: in cxx_eval_store_expression Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: ai.azuma at gmail dot com Created attachment 34133 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34133&action=edit Output of -v option and preprocessed file The following code causes an ICE on 5.0.0 20141123 with -std=c++1y. //========================================== void f(long &c, int &lc, char *&out) { while (lc >= 8) *out++ = (c >> (lc -= 8)); } //========================================== The ICE message is "internal compiler error: in cxx_eval_store_expression", which is the same as one reported in PR64080, so I suspect that this bug report could be a dup. However, the above reproducer looks very different than one in PR64080, so I think this is worth being reported independently. The above code successfully compiles on GCC 4.9.3 20141119 with -std=c++1y, so it seems a regression. The reproducer originally comes from an OpenCV 2.4.10 source code.
