gEDA-user: iverilog & systemC

["michel.agoyan" <Michel.AGOYAN@gemplus.com>]

Hi,
First,  happy new year  !

Few months ago, I have written a simple bus model using systemC and I 
also have done the connection to iverilog using the VPI interface.

Recently I have upgraded  gcc  (2.95.3 -> 3.2.3) . The model as a 
standalone application works well but when I try to use it with iverilog 
it crashes with a segmentation error !

I use iverilog-vpi to compile the shared library (apb.vpi) :

iverilog-vpi --name=apb  -lsystemc -lm   vpi_user.c scib_tvm_vpi.c  apb.o

scib_tvm-vpi.c is the wrapper between the systemC model and vpi

apb.o is the systemC model of the bus built using the command  :
g++ -O3 -fPIC  -c -Wall -Wno-deprecated  -I.  
-I/usr/local/systemc-2.0.1/include  -L.  
-L/usr/local/systemc-2.0.1/lib-linux -o apb.o sc_main.cc  2>&1 | c++filt

The objects that form the model of the bus are global.

Any Idea that can help me ?

Regards
