Some thoughts. When `USE=doc-pdf`, in `src/doc/Makefile` remove respectively, `doc-inventory-reference` and `doc-html-reference` from the targets `doc-pdf-reference` and `doc-pdf-other` and build the docs as ``` emake doc-html PYTHON=${PYTHON} && emake doc-pdf PYTHON=${PYTHON}...

One machine where `sage-doc-9999` from the overlay built. Two machines, one the subject Prefix, needed the `fix` to build.

Changing just `O0` to `O2` gives no SIGSEGV. So, it appears to be optimization.

When I, from sage do ``` sage: enumerate_totallyreal_fields_prim(2,10**4) ``` things look correct. However, when I exit sage there is a backtrace that hangs unless I interrupt things from the keyboard....

`cypari2` uses the `distutils-r1` eclass, which I find a bit mystifying and almost `black boxish`. Is there a way to get output so that one sees exactly what is being...

This all I see here. Perhaps a Prefix thing? ``` Compiling cypari2/string_utils.pyx because it changed. [1/7] Cythonizing cypari2/closure.pyx [2/7] Cythonizing cypari2/convert.pyx [3/7] Cythonizing cypari2/gen.pyx [4/7] Cythonizing cypari2/handle_error.pyx [5/7] Cythonizing cypari2/pari_instance.pyx...

I made too many assumptions. Echoed output is different between Prefix and Gentoo. Gentoo looks fine. I have the debugging enabled on the Prefix

Bug report appears at https://bugs.gentoo.org/818043. The issue seems to occur whenever a `build_ext` is run.
