testRunner issue #24

Open maxsbano opened 5 months ago

maxsbano commented 5 months ago

I describe the output of the testRunner and its backtrace, the executable is not compiled in debug, I cannot trace the assert line:

Moira CPU tester. (C) Dirk W. Hoffmann, 2019 - 2023

The test program runs Moira agains Musashi with randomly generated data.

Test rounds : 1

Random seed : 222

Exec range : (opcode >= 0x0000 && opcode <= 0xEFFF) Dasm range : (opcode >= 0x0000 && opcode <= 0xFFFF)

Round 1:

68000 CPU ................................ PASSED (Moira: 1.28s Musashi: 1.11s)

68010 CPU ................................ PASSED (Moira: 2.62s Musashi: 2.32s)

EC020 CPU ................................ PASSED (Moira: 4.01s Musashi: 3.53s)

68020 CPU .......................

Program received signal SIGFPE, Arithmetic exception.

runned on Windows and Ubuntu, same result

Strange. Hard-coding yesterday's seed (222), it runs flawlessly on the Mac (clang):

Round 1:

68010 CPU ................................ PASSED  (Moira: 1.24s  Musashi: 1.71s)

68020 CPU ................................ PASSED  (Moira: 2.54s  Musashi: 3.48s)

Maybe it's compiler-dependent. Does anybody have gcc at hand and can run the app after compiling it in debug mode?

To hard-code a seed, change this function before compiling: 

int
Randomizer::init()
{
    std::time_t t = std::time(0);
    std::tm* now = std::localtime(&t);

    auto seed = 222; // now->tm_year + now->tm_yday;

    srand(seed);
    return seed;
}

Correct result today....

I don't want to investigate the problem, but it is strange ... Thank you for your time in developing this application ... I want to run an oscilloscope sw!
