Assert.hpp line 33: "Conversion from 'long' to 'unsigned int' requires a narrowing conversion." about type_safe HOT 4 CLOSED

That's really odd. Could you maybe debug and give me a callstack?

from type_safe.

Visual Studio 2017 catches the error before running the project, so I suppose it is a compile-time error. The call hierarchy shows that there are no calls to "on_disable_exception", though there is a long chain of calls from it, seemingly recursive.

Actually I just dug around through "debug_assert.hpp" for a while and noticed "struct source_location" has an unsigned member "line_number". Underneath, a macro is defined which inserts the __LINE__ macro into line_number:

//=== source location ===//
    /// Defines a location in the source code.
    struct source_location
    {
        const char* file_name;   ///< The file name.
        unsigned    line_number; ///< The line number.
    };

/// Expands to the current [debug_assert::source_location]().
#define DEBUG_ASSERT_CUR_SOURCE_LOCATION                                                           \
    debug_assert::source_location                                                                  \
    {                                                                                              \
        __FILE__, __LINE__                                                                         \
    }

Replacing __LINE__ with static_cast<unsigned>(__LINE__) resolves the error and allows me to build and run the project. I am not sure why __LINE__ is of long type, but herein lies the solution.

Oh, sorry, I completely misread your error message.

Could you maybe provide a PR for debug_assert?

from type_safe.

I do not know what a "PR" is, however I did find and provide a solution for the problem at the end of my last comment. Nevermind, you meant "pull-request." I can do that.
