I still see panic in runtime (trace below), segfault in sync, database/sql, net/http and abort in sync/atomic on 32bit CentOS 5.10 library. panic: runtime error: invalid memory address or nil pointer dereference [signal 0xb code=0x1 addr=0x9f] goroutine 1 [chan receive]: testing.RunTests ../../../../gcc-svn/trunk/libgo/go/testing/testing.go:470 testing.Main ../../../../gcc-svn/trunk/libgo/go/testing/testing.go:401 main.main /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/_testmain.go:256 goroutine 64 [running]: goroutine running on other thread; stack unavailable created by testing.RunTests ../../../../gcc-svn/trunk/libgo/go/testing/testing.go:469 goroutine 75 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:261 goroutine 84 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:266 goroutine 82 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:266 goroutine 73 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:261 goroutine 77 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:261 goroutine 80 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:266 goroutine 69 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth /home/uros/gcc-build/x86_64-unknown-linux-gnu/32/libgo/gotest28068/test/map_test.go:261 goroutine 78 [runnable]: created by runtime_test.testConcurrentReadsAfterGrowth [...
