in fact it was a gcc bug.
gcc version 4.1.2 20060530 gives wrong code.
gcc version 4.1.2 20060712 gives correct code.
tree dump shows that gcc-20060530 removes some parts [*] of vector_base
initialization and finally

following reduced testcase works with libstdc++ and segv with stlport.
#include list
#include vector
struct A { };
int main()
{
std::list A* l;
std::vector A* v( l.end(), l.end() );
return 0;
}

The testcase works for me as I don't have the STLport installed (and what is
in
this bug is not enough to reproduce the bug).
so, try latest testcase.
$ make
g++ testDrv.ii -o testDrv

also fails on 64-bit system.
$ g++ testDrv.cpp -o testDrv -pthread -O2 \
-I/usr/include/stlport -nodefaultlibs -lstlport -lc
$ ./testDrv

Well this works with just compiling like:
g++ -O2 -pthread t.ii
With 4.1.0 (4.1.0 20051026).
Yes, it works with libstdcxx but the testcase uses STLport-5.0.2.

Are you sure that you are not mixing operator new and deletes up so the
stlport's operator delete is being called on memory allocated from
operator new from libstdc++?
STLport uses

It works also with 4.1.x -fstrict-aliasing -fno-inline.
