Hi all,
the name of the failing test is 'Making sure the 'char' matrix behaves
like signed byte'. The patch on Ubuntu that fixes the issue replaces
the expected value by another one, but I am not sure if this just hides
the dust under the carpet…
For the record I just have posted that on the GitHub issue:
_bigmemory_ passes the tests on CRAN's `arm64` platforms, which all run
on MacOS. On Linux it fails on `arm64` and a lot of other architectures.
In my understanding, `char` is signed on `macos-arm64` and linux
`amd64` (`x86_64`) and unsigned on linux `arm64`. Would it solve the
problem if _bigmemory_ would pass `-fsigned-char` to the compilers?
Cheers,
Charles
