[vtkusers] Problems on AIX

Wed Mar 20 11:52:09 EST 2002

Hello

Of course it is not a problem of VTK. VTK works fine.
I have another library working with C++ strings.
For example
static const std::string names[10] = { "name1", "name2", ... };

When I'am using above line my program crashes in bastring.h in line 75.
When I'am change std::string to char* my program works but crashes at
the next place where std::string is used.

I have found a similar bug report under:
http://sources.redhat.com/ml/bug-glibc/2001-02/msg00003.html

So I'm assuming that this is a problem of gcc's libstdc++

So I will try to switch to a native compiler first because i don't need
a shared library now.

Bye,
  Alex
