When I did that for a similar problem with the 'sparsesvd' package – before Solaris was available via R-hub, so I really had no chance to chase down the problem without help from CRAN – I never got a response.

I later managed to identify and fix the problem by tedious trial & error via R-hub.

Symptoms were similar: build succeeded, but the package always crashed when running tests and examples, but only on Solaris.

The solution turned out to be that the 3rd-party C code my package wraps defines a C function named store(), which causes Solaris to segfault for reasons that I don't understand at all.  But renaming the function to anything else solved the issue.

Best,
Stefan
