the version of stlport I am using is kind of old, it's stlport4. the compiler I used is CC. platform is solaris.
everytime when my application exits, I got a coredump which happened in ~locale() method, it looks as below.
current thread: t@1
=> std::locale::~locale(0xfeeebab8, 0x1084, 0x1000, 0xfeee28d4, 0x992bc, 0x0), at 0xff27ea04
_exithandle(0xfdbedb80, 0xfe101740, 0xfdbecbc0, 0xfeb46e64, 0xfe111100, 0xfe111140), at 0xfdb408dc
exit(0x0, 0xffbff494, 0xffbff49c, 0x3be800, 0xfe111080, 0xfe1110c0), at 0xfdb2f200
this coredump can be avoid when I remove a code as below.
singleton& s = singleton::Instance();
above code is called in a constructor of a static class member variable as below.
I can't think of why having "singleton& s = singleton::Instance();" will cause a coredump at exit. is it because this line of code cause some problem on the order of descruction? anyone else has runinto this kind of problem?
thanks in advance.
Looks like bad support of C++ in Solaris libs: incorrect order of dtors calls for static object (when I work with Solaris this problem was available). But may be this problem come from you code, possible depends upon the order of unload of shared libs (libstlport unload before lib/app with s).
BTW, if 'incorrect order of dtors' happens, see commits with words like '__cxa_finalize' and '__cxa_atexit' in git repository.
