error in make check of SVC 2.0 (public preview) at AMD64

[vemraete]

Hi,

 

I try to run the 'make check' of the scv-2.0-public_preview and it failed the test 'examples/randomization/constraints'.

I did not see the error at my old 32bit linux box.
However, I do see it with my newer 64 bit linux box.

$ uname -a

Linux debian 3.10-2-amd64 #1 SMP Debian 3.10.7-1 (2013-08-17) x86_64 GNU/Linux

 

I'm using SystemC 2.3.0 and that one should be compiled with 'export CXX=g++ -gPIC'

Could somebody help me?

Hi. 

 

This is (hopefully) a known issue in SCV. It occurs in 64 bit architectures with less than 8++ GB memory available. 

 

The attached patch solves this issue, but it should be used with care. The community developing SCV is not sure for now if this is a fully correct solution.

Hi,

 

Thanks for the patch.  It's passing now.

With the debugger I found out that it's calling twice the construction of the array[CUDD_MAXINDEX].

And I have a machine with less RAM.

 

Strange I could not find any info about the error.  It is so quiet about SystemC in the 'free-world'.

The latest public-review release is quite new and the first occurrence of this error was only ~2 month ago. 

But I agree. It is not always easy to find solutions when you get in trouble with SystemC. But it is getting better. And this forum is a step in this direction by accumulating answers to SystemC-problems.
