I am unable to reproduce this, although I have seen it in the past happen.
Please add a note to this if you are seeing this happen.
On x86_64 (FC6) I can run ./TestRunner -r 1000 frysk.rt.TestUpdatingDisplayValue
and not get any failure at all.
If I do the same on x86 (F7) then I do after some runs I almost always get:
There were 4 failures:
1)
testFuncReturn(frysk.rt.TestUpdatingDisplayValue)junit.framework.AssertionFailedError:
Display is not available
at frysk.rt.TestUpdatingDisplayValue.testFuncReturn(TestRunner)
at frysk.junit.Runner.runCases(TestRunner)

2)

4)
testEnabledExprUnavailable(frysk.rt.TestUpdatingDisplayValue)junit.framework.AssertionFailedError:

at TestRunner.main(TestRunner)
But never the original reported failure. Maybe this new failure is hiding the
original?

The session was on a Fedora 7, x86 machine. Trying to reproduce it on Fedora
Core 6, x86_64 doesn't produce the bug.

Confirmed this is still an issue on x86 (F7), but not reproducable on x86_64
(FC6). Although it now isn't always 4 failures, most of the time it is just one
failure (but sometimes all of the above).

Also not reproducable on x86 F7 even though that machine was used for the demo
from which the attached session comes. sigh.

OK finally reproduced by:
$ frysk/bindir/fhpd frysk/pkglibdir/funit-rt-varchange
Attached to process 404
(fhpd) break @funit-rt-varchange.c@50
breakpoint 0
(fhpd) go
(fhpd) Breakpoint 0 @funit-rt-varchange.c@50
- Now externally from fhpd: $ kill 404
And back in fhpd do a go, which will result in:

Given this assembler:
LOAD_IMMED(REG0,0)
here:
LOAD(REG0,REG0)
set a breakpoint at "here" and then try to step off it. Should result in a
signaled notification with everything looking like it is still at "here".
