The build script in this gist occasionally crashes compiling even the simplest of Go programs (main.go) with the traceback in stderr.log. The strace log corresponding to the crash is in strace.txt.
The build script needs to be invoked with the -c flag because the behavior does not always exhibit.
#Benchmark results created with go test
Test data was generated on a 4-core i7 (16GB ram) Lenovo ThinkPad running Ubuntu 14.04.
Each benchmark was run for 10 seconds (10x the default) to reduce noise seen when the benchmarks ran for 1 second.
go test -run=NONE -bench=Reader -benchtime=10s
I've included the raw test results for each of the master branch, the original pull request, and the pull request modified to avoid heap allocation by inlining the copyWriter struct literal. For the latter two I've included benchcmp output comparing them to the master branch. There is also a comparison between the pull request and it's modified form.
