897.0. "seg fault debugging STL ctor" by TLE::WHITMAN () Mon Mar 24 1997 11:08

hi,

I am running on:

    OSF1 cxxosf.zko.dec.com V4.0 564 alpha

My cxx line is:        

    cxx -g prog.cxx

The cxx version is:

    DEC CXX X5.6-121 on Digital UNIX (Alpha)

Here's the program:

#include <list>
typedef list<int> IntList;

int main ()
{
   IntList a;
   return 0;
} 

If I try to step through the construction of IntList a I get:


      6    IntList a;

Fatal error: Segmentation fault


I didn't try to reduce the program  further.
    

Thanks for the report.  I've added it to the C++ bugs list.
