Is anyone else seeing comparison problems on trunk?
I was having problems testing a patch on a 4/16 extraction, so last
night I checked out a fresh trunk, built it, ran make check... then
removed the build directory, re-built it from scratch again. make
check.. and get a bunch of different results. I even used
test_summary instead of my own home-grown scripts.
Its not ordering this time, its actual reported failures on
x86_64-unknown-linux-gnu... for instance,
run 1 found, among other things:
PASS: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 80)
FAIL: g++.dg/cpp0x/rv1n.C -std=c++14 (test for warnings, line 84)
PASS: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 89)
PASS: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 91)
FAIL: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 92)

FAIL: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 95)
<...>
but in run 2, those results were fine, but instead a different set of
failtures showed up, like:
PASS: g++.dg/cpp0x/udlit-implicit-conv-neg.C -std=c++11 (test for
errors, line 47)
PASS: g++.dg/cpp0x/udlit-implicit-conv-neg.C -std=c++11 (test for
errors, line 49)
PASS: g++.dg/cpp0x/udlit-implicit-conv-neg.C -std=c++11 (test for

errors, line 55)
FAIL: g++.dg/cpp0x/udlit-implicit-conv-neg.C -std=c++11 (test for
errors, line 57)
<...>
I see in the log, it looks like something got truncated in the output
from the compiler:
/home/amacleod/gcc/2015-04-21/gcc/gcc/testsuite/g++.dg/cpp0x/rv1n.C:89:27:
error: use of deleted function 'constexpr A::A(const A&)'^M
/home/amacleod/gcc/2015-04-21/gcc/gcc/testsuite/g++.dg/cpp0x/rv1n.C:91:28:
error: use of deleted function 'constexpr A::A(const A&)'^M
/home/amacle
PASS: g++.dg/cpp0x/rv1n.C -std=c++14 (test for warnings, line 34)
PASS: g++.dg/cpp0x/rv1n.C -std=c++14 (test for errors, line 39)
so the rest of the compiler output for that execution is not in the log,
so a bunch of FAILS are reported since the messages aren't showing up.
Is there another known issue with mashing together multiple outputs, or
truncating long output? I'm using -j16 ... Is there something else I'm
missing? its clearly been an issue for almost a week at least
It appears to be mostly the gcc and g++ results.
