Workaround:

Hide
No simple workaround. If there's a way to restructure the code to avoid template parameter packs, or at least to avoid passing them as arguments to calls, try that. This particular test case will not crash with -O2 or -O3, though it will with -O0 and -O1. The --disable_inlining option will avoid the problem, but of course affects performance.

Release Notes:
When compiling C++ code that uses template parameter packs, especially if those parameter packs are passed as arguments to calls within the template functions, the optimiser may crash.

Optimizer fails with segmentation fault
