Internal compiler error on TravisCI when compiling Modules.cpp

Interfaces RStan

I am trying to convert packages using rstan to 2.16.2. Some problems encountered have been solved:

thanks to @bgoodri, @helske and a trick by Dirk Eddelbuettel.

Two packages (the sample Travis CI - Test and Deploy with Confidence and the real one with only one stan model Travis CI - Test and Deploy with Confidence) work ok, both with clang-5.0 and gcc-6. A third package Travis CI - Test and Deploy with Confidence with multiple stan files fails with

ERROR: compilation failed for package ‘gastempt’

Same error with gcc and clang. I suspect an out-of-memory condition, but how to test this and what to do against it? The package compiled ok with stan1.5.2 and is on CRAN.

Yeah, that is hitting the memory limit of the machine. You could try compiling with -Os instead of -O2.

Using sudo:required gives more memory, and is not as slow as it used to be.
