Description
I'm aware this is for old-ish version of Go, but thought better to report than not, you can always just close it. Highly non-deterministic, this app usually runs well, but I think I've already seen it crash in a somewhat similar way once over last 1-2 months. No "import C", no "go whatever()" in code. Generally run as a parser for go test -v
(got ~20MB file as input this time), tries to split it and pass into text/template. (Actually planning to open-source the particular code soon-ish, but can't just yet.)
