[Bioc-devel] error on riesling1 but not on palomino3

[Oleksii Nikolaienko]

Dear Bioc team,
my package (epiallleleR) currently fails tests on riesling1, but not on the
other hosts. Wrong results are produced by compiled c++ code, and at the
moment I don't understand why. I can see that both Windows hosts use GCC
8.3.0, but the compiler flags are different. I don't have access to
Windows, but I wasn't able to reproduce this error on my Linux with GCC
7.5.0 when tried to set "-fno-reorder-blocks-and-partition" in my Makevars,
or did "pkgbuild::with_debug(devtools::check())".
What are the other differences between riesling1 and palomino3? Is, for
example, sizeof(int)<4? And what can I do to debug it if I don't have
Windows around?

Best regards,
Oleksii
