Yes, pretty much - the actual value of the address of `&val` isn't known at compile time and it cannot be produced in a way to initialize e.g. static memory, which I would believe that one can expect of constexpr. The runtime linker that loads DLLs can't fix it so that the address is available as a statically initialized data, but to use it it does require runtime code to fetch the address. > Without constexpr the symbol generated is > > 0E 00000000 UNDEF notype External | __imp_?val@@3HA > (__declspec(dllimport) int val) > > and the assembly generates a ‘load __imp_? Val’. Same than MSVC, but the test > case fails to run. @rnk Shouldn't this run? Can you give the full exact repro for this case, without constexpr, which you say fails to run - I tried to follow the instructions but for me it seems to work just fine, without constexpr.
