Hi there,
after becoming able to create the 32-bit ooRexx interpreter from trunk, I
started to test it with
BSF4ooRexx programs.
One rather complex JavaFX-application implemented in ooRexx causes an exception
in isObjectMarked().
Here is top of the Java hs_error_pidNNNN.log file which gives a stack trace
exploiting the available
debug symbols:
# # A fatal error has been detected by the Java Runtime Environment: # #

The JavaFX program is an experimental ooRexxTry.rxj (an ooRexx program using
JavaFX for its GUI),
which will cause a crash while executing the following code:
trace i; do i=1 to 55; say 55/i; end;
.output, .input, .error, .traceOutput, .debugInput are redirected, such that
the student becomes
able to colorize the .traceOutput. Sometimes the above program runs
successfully, most of the time
it crashes on the first run.
Here is the colored trace output when the above program runs successfully
making it easy to
distinguish the trace from the regular output:
1 *-* do i=1 to 55; >L> "1" >L> "55" >=> I <= "1" >>> "1" 1 *-* say 55/i;
>L> "55" >V> I => "1"
>O> "/" => "55" >>> "55" REXXout>55 1 *-* end; 1 *-* do i=1 to 55; >>> "1"
>>> "2" 1 *-* say
55/i; >L> "55" >V> I => "2" >O> "/" => "27.5" >>> "27.5" REXXout>27.5 1 *-*
end; 1 *-* do i=1 to
55; >>> "2" >>> "3" 1 *-* say 55/i; >L> "55" >V> I => "3" >O> "/" =>
"18.3333333" >>>
"18.3333333" REXXout>18.3333333 ... cut ... 1 *-* end; 1 *-* do i=1 to 55;
>>> "53" >>> "54" 1
*-* say 55/i; >L> "55" >V> I => "54" >O> "/" => "1.01851852" >>>
"1.01851852" REXXout>1.01851852
1 *-* end; 1 *-* do i=1 to 55; >>> "54" >>> "55" 1 *-* say 55/i; >L> "55"
>V> I => "55" >O> "/"
=> "1" >>> "1" REXXout>1 1 *-* end; 1 *-* do i=1 to 55; >>> "55" >>> "56"
On one occasion I was able to get into the debugger which reported an
unauthorized write to a memory
location, here is the call stack from the VS debugger:
