Jin Qing commented on LOGCXX-416:
---------------------------------
It crashes on a normal log4j.xml.
Tested on:
x86_64-redhat-linux
gcc 4.4.5
Red Hat Enterprise Linux Server release 6.1 (santiago)
Got crash on VC2010Express also.
log4cxx Revision: 1559537
apr-1.5.0-win32-src.zip
apr-iconv-1.2.1-win32-src-r2.zip
Link log4cxx static.
No crash if using log4cxx.dll.

> Project: Log4cxx
> Issue Type: Bug
> Components: Configurator
> Affects Versions: 0.10.0
> Reporter: Jin Qing
> Assignee: Joseph Southwell
> Priority: Critical
>
> On exit(), FileWatchdog::checkAndConfigure() calls apr_pool_creae() and crash.
> Test code:
> #include <log4cxx/xml/comconfigurator.h>
> class A
> {
> public:
> A() {};
> ~A() {
> for (int i = 0; i < 1000000; i++)
> for (int i = 0; i < 1000000; i++)
> ;
> }
> } g_a;
> int main()
> {
> log4cxx::xml::DOMConfigurator::configureAndWatch("log4j.xml", 1000);
> return 0;
> }
> After main() returned, but main thread is still running, watchdog thread
> will crash when checkAdnConfigure().
