--- Comment #1 from Ian Lance Taylor <ian at airs dot com> ---
I can not recreate this problem. It works fine for me.
The stack trace is incomplete for some reason so I don't know what is going
wrong.
If you cd into x86_64-pc-linux-gnu/libgo, you can run
make GOTESTFLAGS="--keep" reflect/check
Presumably that will fail. It will leave behind a gotestNNNN directory. In
that directory you will find an a.out executable. Running that executable runs
the test (you may have to set LD_LIBRARY_PATH so that it finds libgo.so). Try
running that executable under gdb and see if you can get a better backtrace.
