Compiler error with GCC 11.3: template argument deduction failed

[carlosgalvezp]

Hi!

I'm using commit 8fafda42e732164db58003e542196e94a28481f9 of rapidcheck, building on C++14 mode. When trying to bump the compiler to GCC 11.3.0 (from GCC 7.5.0) I get the following compile error:

This happens when calling the function rc::gen::inRange<int>(0, N).

Do you have any feeling for what might be going on? Thanks!
