Travis build errors

[Majkl578]

There is a lot of borked builds for PRs on Travis (https://travis-ci.org/facebook/hhvm/pull_requests), e.g.:

g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.8/README.Bugs> for instructions.
make[2]: *** [hphp/compiler/CMakeFiles/hphp_analysis.dir/package.cpp.o] Error 4
make[2]: *** Waiting for unfinished jobs...

How about changing time make -j 6 to time make -j 6 || time make -j 6 in .travis.yml? So it can try to build again. Decreasing the job numbers in the 2nd try may also help.

maybe it ran out of memory? that's the same error i'd get before i setup a swap file on my vm.

@jrobeson travis disabled by default swap, so he immediately after memory leaks crashed!
travis-ci/travis-ci#1972 (comment)

Alas travis does not provide a machine of ubuntu 14.04 with more fresh toolkit (lose some opportunities laying, and more stable components)..

builds have 3 GB of memory available

sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

g++ .....

sudo swapoff /swapfile
sudo rm /swapfile

• C++11: g++-4.7 internal compiler error

[jwatzman]

@paulbiss @sgolemon why do we even still have the travis config? It's consistently broken and we ignore it anyways. Should we just remove it?

[denji]

@jwatzman It would be better if fb has offered its version of travis to check the pull request and live migration.

[jrobeson]

the travis configuration has been dropped from HHVM as of 658ca01 so this issue should be closed
