[R-pkg-team] Bug#1013984: r-cran-v8: configure assumes V8_COMPRESS_POINTERS=true but it is not

[Jérémy Lal]

Source: r-cran-v8
Version: 4.2.0+dfsg-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

When building r-cran-v8 against nodejs 18.4.0 in experimental,
this happened:
# Fatal error in , line 0
# Embedder-vs-V8 build configuration mismatch. On embedder side pointer compression is ENABLED while on V8 side it's DISABLED.

It is true that nodejs is built with V8_COMPRESS_POINTERS=false,
so r-cran-v8 detection has a problem.

This will prevent migration of nodejs 18 to testing,
so I'll gladly make a quick patch to fix the build.
