Re: [Discuss-gnuradio] error

[Martin Dvh]

Using gcc-3.,3 I got to debug the tests, I also now come a little bit furter in 
the test_runtime.
I uninstalled gnuradio before doing the test. I thought the tests where selfcontained in the source directory but apparantly it sees and uses 
the installed gnuradio library. (This didn't help for the gcc-3.4 case, I still get a segfault probably because of cppunit not compiled with 
gcc-3.4)

Now I get a SIGBUS which results in an ABORT in lt_test_runtime (and other 
tests)
This is when it tries to fill the memory and is about halfway the allocated 
shared memory buffer.


gr_vmcircbuf.cc:
static void
init_buffer (gr_vmcircbuf *c /*c=0x7d56000*/, int counter 
/*counter=131076096*/, int size /*size=4194304*/)
{
  unsigned int *p = (unsigned int *) c->pointer_to_first_copy ();
  for (unsigned int i = 0; i < size / sizeof (int); i++)
    p[i] = counter + i;//This is gr_vmcircbuf.cc:124.  SIGBUS here when i== 
348160
                       // while it should continue untill i=4194304/4=1048576
                       //The testprogram will now Abort
}

Greetings,
Martin
