Dear List, my recent upload of dqrng v0.1.0 has triggered an ERROR on Solaris:¹ One of the new tests results in a segmentation fault. During this test some C++ code is compiled using Rcpp::sourceCpp and the resulting functions are being called for different input.
Unfortunately I cannot reproduce the error on rhub's Solaris machine.² I find it interesting that on both platforms a (IMO false positive) warning is emitted by the compiler, but the wording is quite different. Does this mean that the C++ compiler from Oracle Developer Studio is used on CRAN? From https://www.stats.ox.ac.uk/pub/bdr/Rconfig/r-patched-solaris-x86 I had gathered that g++ would be used for building packages that link with Rcpp. But maybe that does not apply to code being compiled during tests of such packages? Anyway, I do not want to risk the package getting archived for failure of fixing this cross-platform issue. Does anybody have suggestions for reproducing such issues? Any other suggestions how to proceed?
