它可以在几分钟前成功编译.在我尝试通过按"配置文件"按钮构建项目之后出现了问题.之后,我的项目无法再编译.

错误消息是:

我想在跟踪程序捕获异常的一些信息时遇到问题.

我使用了以下功能:

extern "C" void log_backtrace()
{   
    // Dump the callstack
    int callstack[128];
    int  frames = backtrace((void**) callstack, 128);
    char** strs = backtrace_symbols((void**) callstack, frames);

    for (int i = 1; i < frames; ++i)
    {
        char functionSymbol[64*1024];
        char moduleName    [64*1024];
        int  offset        = 0;
        sscanf(strs[i], "%*d %s %*s %s %*s %d", &moduleName, &functionSymbol, &offset);
        int addr = callstack[i];
        int   validCppName;
        char* functionName = abi::__cxa_demangle(functionSymbol, NULL, 0,
                                             &validCppName);
        if (validCppName == 0)
            printf(   "\t%8.8x — %s + %d\t\t(%s)\n", addr, functionName, offset, …
