[R-pkg-devel] Handling ERROR on Solaris

[Ralf Stubner]

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?

Thanks
Ralf
