Ran into a "virtual memory exhausted" error

[ubugnu]

I created a fresh rails 5.2.0 app with:

rails new test_app

Then I executed:

./rubyc test_app/bin/rails

I get:

...

compiling addr2line.c

compiling localeinit.c

8G of virtual memory exhausted, not normal!

hi, I use rubyc too, please wirte how much your memory sum RAM+Swap? I think 10 GB would be OK. In my case I have 6 GB RAM and 4 GB Swap and prelude.c compiling use almost all it memory. Also I tried to change swap to 6 GB (sum 12 GB).

I think I ran into this, I have 32 GB RAM and I found while compiling prelude.c I had a clang process that had chewed through 62 GB of RAM so I killed it off before it took the whole machine down.

I am compiling a tiny Ruby script. It takes like half an hour and in the end:
