[Rcpp-devel] Rcpp Module Errors

Module('yada','test')$ ...

bla()

library(test)

test::

I apologize if this has been covered.  I've looked and see a couple of post
relating to this issue, but I'm not sure if it was ever solved. The example
modules appear to not work, at least for me.  On a related note I can't get
my modules to run either, but If I can figure out how to run the examples I
think I can get mine running.

Adding Rcpp settings

and check with an error.
$R CMD check test_1.0.tar.gz

... WARNING
Error: .onLoad failed in loadNamespace() for 'test', details:

According to Dirk's June 15th post on the issue I include require("methods",
character=TRUE, quietly=TRUE) in the .onLoad function, now checks ok but
when trying things out I get a segmentation fault.
$ R -q --vanilla
R> library(test)
Loading required package: Rcpp
R> Module('yada','test')$bla()

 *** caught segfault ***
address 0x90, cause 'memory not mapped'

Traceback:
 1: .Call(symbol)
 2: Module(module, mustStart = TRUE)
 3: .getModulePointer(x)
 4: Module("yada", "test")$bla

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

So questions are:
    1) is anyone else getting this error?
    2) does anyone know how to fix it?

Thanks,
Andrew
