None of these look familiar to me.
An "Epoll unexpected fd" error means that epoll returned information
about a file descriptor which the program didn't ask about. Not sure
why that would happen. Particularly for fd 0, since epoll is only used
for network connections, which fd 0 presumably is not.
The way to look into these is to cd to TARGET/libgo and run "make
GOTESTFLAGS=--keep http/check" (or whatever/check). That will leave a
directory gotestNNNN in your libgo directory. The executable a.out in
that directory is the test case. You can debug the test case using gdb
in more or less the usual way. It's a bit painful to set breakpoints by
function name, but setting breakpoints by file:line works fine.
Printing variables works as well as it ever does, but the variables are
printed in C form rather than Go form.
