[R-pkg-devel] R package manual failing only on R-devel-linux-x86_64-debian-gcc

[Zhian Kamvar]

Hello,

I'm having a really strange problem that I cannot reproduce locally (Ubuntu
bionic) or on Rhub. I've run into an issue where the R package manual is
failing only on this platform with ancient LaTeX runes that I struggle to
decipher [0]

The only information I could find on the error was a question with answers
that were more questions: https://stackoverflow.com/q/2765229/2752888

Uwe Ligges was kind enough to trigger a second build to see if this was an
anomaly, but the same incantation appeared again. I've tried building this
on Rhub debian-devel-gcc, but could not reproduce the error [1] and no
other platform does this.

Has anyone seen this before?

Thanks,
Zhian
