[R-pkg-devel] IFC package - Solaris error polygon edge not found (zero-width or zero-height?)

[git demont]

Replying to myself and with some additional investigations

I just tried once again on rhub - Oracle Solaris 10, x86, 32 bit, R-release
and got the same error with a conditional font family modification where
when
Sys.info()["sysname"] == "SunOS",
- pdf(), family argument is set to its default value "Helvetica"
- gridExtra::ttheme_default, base_family argument is se to its default
value ""
Otherwise, "serif" is used

In addition, the error in solaris shares "polygon edge not found" lately
reported by Iñaki Úcar
Though, I don't have the warning part, and mine is not happening during
vignette rebuilding
