No one can it seems.
No one except those that can reproduce the problem and then isolate it.
Please don't expect me to download Slowlaris, install it in a PC,
install the right GCC and binutils, and then cross my fingers that the
problem happens for me too.

Right, I was thinking the same thing. What changed here? That was my first
mpf/eq.c <-- this is new.
Eh, you misunderstood. What does gcc -v and g++ -v output? (Assuming
you don't pass CC=some-other-gcc without CXX=the-same-g++.)
Not the same as what I used for my builds on Sparc.
I have a patch from you regarding that. Not really a patch. More like a
whole new file. Turns out, nothing other than the arch and that one source
It seems unlikely that the eq rewrite casuses these three cxx failures,
but as a professional software engineer, you could of course back out
the eq.c change for now.

Right. That makes sense but the test harness is a bit obfuscated.
Now, now. When it says "FAIL foo ... Leaving directory bar", perhaps
try "cd bar; ./foo". It'll work, and it'll give you the failure
slightly more verbosely.
At the very least it is not easy to get in there and just do these
things myself knowing what I am supposed to get. I don't have
testsuite docs to refer to that say "run test foo and see result
output data bar".
The testsuite is documented as a bunch of files with the extension ".c".
(I really doubt you need to understand anything about the test suite in
order to isolate a failure.)
