Would people be interested in having a parallel version?
Cool! I'll look into this. Just as I was thinking that the parallel build problems are solved, the issue surfaced again. I've attached a complete, unmodified log to this mail. Some notes: - asap-clang is a wrapper around Clang that I use for a research project. It should behave the same way as Clang in this case. If anything, it might be less threadsafe. - commands such as configure_and_build_python are from a shell script that invokes configure, make, etc. - This is running on Ubuntu 14.04 with Clang 3.5 and GNU Make 3.81, and a fresh checkout of Python 3.4 - I see two compiler invocations for Parser/pgen.c . Not sure why this happens. It seems to cause the pgen.o file to be empty or truncated. Any ideas? Cheers, Jonas
