So the compile that command that failed is printed right above the
error message it generated. (The long line that starts with
'gcc' ...). I just copied this command, edited the -O3 to an -Os, and
pasted that command-line back into the terminal. Total low-tech hack,
as I didn't want to much with the setup.py file to fix compile flags
on a per-file basis.
After that file is compiled manually, you can re-run 'python setup.py
build', and it will start up at the next step after the error.
I got the same error in another step, which was a bit trickier to fix,
because for some reason, src/_image.cpp gets copied to src/image.cpp
on a temporary basis, and then compiled. (I presume the file isn't
also modified?) But after the compile errors out, the copy is deleted,
so just pasting in the offending gcc command doesn't work. So I had to
manually copy src/_image.cpp to scr/image.cpp, and then paste in the
modified gcc command.
Ugh! I'd really love some help reducing this to a test case that I can
send to Apple.
