Hi,

I tried to reduce this to a minimal case here: https://godbolt.org/z/36co5a

Similar cases where I can't repro the crash:
- compile with std c++98, 11 or 14 (crash for 17, 20, 2a).
- Having data0 in class bar, or in global scope
- bar without template
- move bar ctor to a free function without template

Moving bar ctor to a free function with template gets a linker error:

Bye,
JB.
