segmentation fault in 1.7.0 #408

Open aumer-logiciel opened 5 months ago

aumer-logiciel commented 5 months ago

I have a legacy application that is using the quill version 1.7.0 and is giving segmentation fault as soon as I try to log something.

My code:

ACE_INT32 main( ACE_INT32 argc, char * argv[] )
{
    //Moved in Start Server function
    ////MA_20230511 - quill
    quill::Handler* file_handler = quill::file_handler("Engine-Quill.log", "a", quill::FilenameAppend::Date);

    file_handler->set_pattern(
        QUILL_STRING("On %(ascii_time) by (%(process)|%(thread)) - %(message)"), // log recorder format
        "%Y-%m-%d %H:%M:%S.%Qus",     // timestamp format
        /*quill::Timezone::GmtTime*/ quill::Timezone::LocalTime); // timestamp's timezone

    // This line sets the default logger's handler to be the new handler with the custom format string
    quill::set_default_logger_handler(file_handler);

    quill::start();

    // quill::Logger* logger = quill::get_logger();
    // logger->set_log_level(quill::LogLevel::TraceL3);

    // LOG_TRACE_L3(logger, "This is a log trace l3 example {}", 1);

    while (1) {
        sleep(1);
        printf("yo\n");
        LOG_INFO(quill::get_logger(), "yoyo");
    }
}

It crashes as soon as the first statement is executed.

yo
Segmentation fault (core dumped)

Hi @odygrd could you please look at this ? Thank you!

odygrd commented 5 months ago

I could not reproduce on my machine.

It is not possible for that simple example to crash in 1.7.0 that would mean the library is not working at all and there were many unit tests.

It should be something related with your system or specific OS.

This code is part of a huge legacy application that has a lot of other dependencies to it. The thing is when I run it separately it works alright as well but combined with the application it crashes instantly. In my application I have placed this code at the top of the main function so as to not affect it by other components but still it is giving me this error continuously.

odygrd commented 5 months ago

are you linking your own version of lib fmt in your final application ? Just a suspicion

aumer-logiciel commented 5 months ago

I am using bundled fmt of quill @odygrd

odygrd commented 5 months ago

Are you also using your own libfmt outside the logger linking the whole program against?

Can you try to link the standalone example that you say it's working with the same libraries you're linking your application and see if it works ?
