Why does running the tutorial example fail with Rstan?

I installed the RStan successfully, the library loads. I try to run a tutorial example (https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started#example-1-eight-schools). After applying the stan function

fit1 <- stan(
  file = "schools.stan",  # Stan program
  data = schools_data,    # named list of data
  chains = 4,             # number of Markov chains
  warmup = 1000,          # number of warmup iterations per chain
  iter = 2000,            # total number of iterations per chain
  cores = 1,              # number of cores (could use one per chain)
  refresh = 0             # no progress shown
)

I get the following error:

*Error in compileCode(f, code, language = language, verbose = verbose) : 
  C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file1c34165764a4.o:file1c34165764a4.cpp:(.text$_ZN3tbb8internal26task_scheduler_observer_v3D0Ev[_ZN3tbb8internal26task_scheduler_observer_v3D0Ev]+0x1d): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file1c34165764a4.o:file1c34165764a4.cpp:(.text$_ZN3tbb10interface623task_scheduler_observerD1Ev[_ZN3tbb10interface623task_scheduler_observerD1Ev]+0x1d): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file1c34165764a4.o:file1c34165764a4.cpp:(.text$_ZN3tbb10interface623task_scheduler_observerD1Ev[_ZN3tbb10interface623task_scheduler_observerD1Ev]+0x3a): undefined reference to `tbb::internal::task_scheduler_observer_v3::observe(bool)'C:\rtools42\x86_64-w64-mingw32.static.posix\bin/ld.exe: file1c34165764a4.o:file1c34165764a4.cpp:(.text$_ZN3tbb10interface
Error in sink(type = "output") : invalid connection*

Simply running example(stan_model, run.dontrun=T) gives the same error.

What does this error mean?

Is rtools wrongly installed? My PATH seems to contain the correct folder C:\\rtools42\\x86_64-w64-mingw32.static.posix\\bin;. Is something wrong with the version of my Rstan package? I am struggling to interpret this error?

What to try to solve it?

Apparently Rtools42 in incompatible with the current version Rstan on CRAN. The solution that worked for me is found here: https://github.com/stan-dev/rstan/wiki/Configuring-C---Toolchain-for-Windows#r-42
