Package: duma
Version: 2.5.15-1
Severity: normal

Hi Julien, 

I just tried to use duma for a simple buffer overrun example. However, I was unable to use the "duma" command:

torsten@pulsar:~/strbuf_protect$ duma ./example
ERROR: ld.so: object './libduma.so.0.0.0' from LD_PRELOAD cannot be preloaded: ignored.
[program output...]

However, setting LD_PRELOAD manually works:

torsten@pulsar:~/strbuf_protect$ LD_PRELOAD=/usr/lib/libduma.so.0.0.0 ./example

Identifier 0 maps to name foo.
Buffer too small for name of identifier 1.
Segmentation fault

I am wondering over the segfault (valgrind detects the error, but electric fence segfaults as well) - the example overwrites some hundred bytes after the end of the buffer.

Greetings, Torsten
