关于程序退出后log4cxx的LoggerPtr变量造成崩溃的问题

时间：2010-07-13

来源：互联网

目前程序中使用了log4cxx，初始化过程是：

LoggerPtr p_log
const log4cxx::LogString conversionPattern =
"%d{%m/%d/%y %H:%M:%S} [%t] %-5p - %m %n";
log4cxx::PatternLayoutPtr layout = new log4cxx::PatternLayout(
conversionPattern);
log4cxx::ConsoleAppenderPtr console(layout);
log4cxx::RollingFileAppenderPtr file(new log4cxx::RollingFileAppender(
layout, log4cxx::LogString(filename), true));
file->setMaxBackupIndex(logMaxBackupIndex);
file->setMaxFileSize(log4cxx::LogString(logFileSize));
log4cxx::helpers::Pool p;
file->activateOptions(p);
p_log = log4cxx::Logger::getLogger("./setup.log");
p_log->addAppender(file);
p_log->addAppender(console);
p_log->setLevel(log4cxx::Level::getTrace());

复制代码

但是程序退出时，会造成崩溃，coredump中的堆栈如下，请朋友们解决帮助，非常感谢！

log4cxx很少人用吗？
