Most likely you ran out of RAM. On Linux, it is fairly straightforward to temporarily add -flto to CXX14FLAGS in the ~/.R/Makevars file, which may help with the RAM spike.

When you run low on RAM, the system will grind to a halt and even if it is progressing, it may or may not be able to get additional output...

@akucukelbir or @dustinvtran Do you have access to a Windows machine to reproduce this? Change weibull.txt to weibull.stan and weibull.data.txt to weibull.data.R .

The backtrace is related to the streaming ``` #2 0x00514a70 in std::ostreambuf_iterator std::num_put::_M_insert_float(std::ostreambuf_iterator, std::ios_base&, char, char, double) const () ```

What Bob said. I'm continuing to guess that it tried to stream a double that was too big. If that is correct, could we use scientific notation or something for...

We do have a Windows machine. You might be able to write a unit test that just streams a million random characters in the same way that ADVI does. On...
