thanks. Testing has now concluded as well. x86 results are good (no
regressions except for cmd/internal/buildid which fails on Linux, too),
as are 64-bit sparc results. However, 32-bit sparc shows lots of
execution failures:
* There's
FAIL: go.go-torture/execute/chan-1.go execution, -O0
at all optimization levels, with
fatal error: all goroutines are asleep - deadlock!
goroutine 1 [chan send]:
main.main
/vol/gcc/src/hg/trunk/local/gcc/testsuite/go.go-torture/execute/chan-1.go:5
* but the vast majority of failures are like
FAIL: go.test/test/blank.go execution, -O2 -g
panic: runtime error: invalid memory address or nil pointer dereference
