ARM segfault while generating inference.ji

[eschnett]

I'm building Julia 0.5 (master) on my Raspberry Pi. This aborts with

make[1]: Entering directory '/home/pi/src/julia-0.5'
 cd /home/pi/src/julia-0.5/base && /home/pi/src/julia-0.5/usr/bin/julia -C arm1176jzf-s --output-ji /home/pi/src/julia-0.5/usr/lib/julia/inference.ji --startup-file=no coreimg.jl

duplicate of #17577?

[yuyichao]

More likely #17645

[eschnett]

#17645 shows the same symptoms, but the remedy there didn't help. I'm using USE_SYSTEM_LLVM=1, with LLVM 3.7.0. Is that a bad idea?

[nalimilan]

In my experience USE_SYSTEM_LLVM=1 makes inference fail on ARM (#10602). It would be interesting to know whether somebody managed to get the build pass on ARM with that option set.

[yuyichao]

I'm using USE_SYSTEM_LLVM=1 with either llvm SVN/patched 3.7.1/alarm stock 3.8.0.

Looks like the buildbot successfully built a binary a few hours ago. I wonder if this is spurious or if the issue got addressed with the recent arm PR and other compiler PRs.

@josefsachsconning Can you test on your setup?

[josefsachsconning]

My build has been running for 2.5 hours on my Raspberry Pi. Looks like it's using a lot more memory than it used to, swapping a lot on my 1 GB system.

My build just went through and is failing:

signal (11): Segmentation fault

*** This error is usually fixed by running `make clean`. If the error persists, try `make cleanall`. ***

Perhaps I am filing this in the wrong issue.

[josefsachsconning]

The build is being killed by oom-killer on my 1 GB Raspberry Pi 3. I'll try again after I connect a USB hard drive and add swap space on it.

[josefsachsconning]

I have added swap to my Raspberry Pi, and successfully built 0.6.0-dev.212.
