all.bash: go tip failure on Raspberry Pi B+ (armv6l) #11785

Closed jonathanpittman closed 9 years ago

jonathanpittman commented 9 years ago

I am using go1.4.2 and trying to build go at tip on a Raspberry Pi B+ with 512MB RAM (16MB allocated to video, the rest to the system). I am synced to commit "e1ee314 internal/trace: fix fuzzer crashers".

I am getting this when running all.bash at tip. It was happening before 1.5 beta 1 and is still happening. I had no problems building 1.4.2 from source (which is what is being used for the bootstrapping).

Linux raspberrypi 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux
