Summary: test bfin-elf via simulator, it stops in gdb.gdbtk/c_variable.exp with case "stop in subroutine1"
Details:
When test bfin-elf via simulator, gdb test stops in gdb.gdbtk/c_variable.exp with test case "stop in subroutine1". I have to kill the test pid in the background as the test can not continue.
Last passed time is on Mar 29th, 2010. And it fails after that.

In gdb.log, we can see it stops after case "check whether linteger -- lsimple.integer changed (c_variable-2.8)" is passed.
The next case is "stop in subroutine1 (c_variable-2.9)".
check_update
==== Result was:
lpcharacter {}
++++ c_variable-2.5 PASSED
==== c_variable-2.6 check whether llong -- lsimple.character changed
==== Contents of test case:
{lsimple.character lsimple.integer lfloat lpfloat llong lplong ldouble lpdouble} {}
++++ c_variable-2.6 PASSED
==== c_variable-2.7 check whether lsimple.signed_character, lsimple.char_ptr, lpsimple, func changed
{lpsimple func lpsimple->integer} {}
++++ c_variable-2.7 PASSED
==== c_variable-2.8 check whether linteger -- lsimple.integer changed
{lsimple.character lsimple.integer lcharacter linteger lfloat llong lpsimple->integer ldouble} {}
++++ c_variable-2.8 PASSED
(it stops here)

I see things being run - but I'm not sure where it's getting stuck...

It seems to be working OK - but the file doesn't ever close.

when it stops like that, it has most likely displayed something in the X session
and the select() is actually waiting for user input (click a button). best
thing would be to install something like scrot and take a snapshot of it.
$ pgrep -lf Xvfb
5026 Xvfb :1464 -ac
$ DISPLAY=:1464 scrot snap.png
then post that snapshot as an attachment, or look at it yourself to see what it
wants ...

i was hitting a problem, but turned out to be unrelated (committed a fix for it
at any rate). current svn trunk passes the same way for me as it always has. a
few tests fail, but they've always failed. i certainly dont see the hang as
reported here. please run that scrot stuff to see what's going on in your Xvfb.
another option might be to vnc into it via x11vnc, but that's more
complicated.

Yeah - this looks like it works for me now...

It works for me too.
So close this bug.
