Package: g++-4.3
Version: 4.3.1-2
Severity: normal

Hello,

while trying to investigate why libept does not build on ARM, I came up
with the attached source code.  On any system, it gives a link time
error while building it.  On ARM, only when invoking g++, only with
-fPIC, it links fine, then running the program segfaults.

To reproduce, install g++ 4.3 on ARM, then run:

  g++-4.3 -fPIC -o main1 main1.cpp

We have been working on minimising this test code since a whole day, and
we did not manage to make it smaller than this.  Fiddling with this code
further (like removing a template parameter, or removing the std
namespace) makes the linker error properly appear.


Ciao,

Enrico
