[Oorexx-devel] Crash with interpreter at rev 1376

[Mark M. <mie...@gm...>]

Hi Rick,

Thought I'd start a new thread.

With the interpreter at the latest level (1376)

The crash is here:

bool RexxInternalObject::isBaseClass()
{
    return behaviour->isPrimitive();
}

With the this pointer looking invalid: this	0xe2912357


Here is the stack trace


rexx.dll!RexxInternalObject::isBaseClass()  Line 176 + 0x3 bytes
rexx.dll!RexxObject::requestArray()  Line 1263 + 0x8 bytes

I can reproduce it with the program I posted before:

world=.WorldObject~new
msg1=world~start("HELLO")                /* same as next line     */

say 'Going to use SysSleep() for 1 seconds before starting message 2'
j = SysSleep(1)
say 'Back from SysSleep()'


msg2=.message~new(world,"HELLO")~~start  /* same as previous line */

say msg1~result           /* Produces Hello world 21:04:25.065000 */
                          /* for example                          */
say msg2~result           /* Produces Hello world 21:04:25.081000 */
                          /* for example                          */

::class 'WorldObject' public
::method hello
  return "Hello world" time('L')

I get the same stack trace each time, with the this pointer an invalid
address, but a different address each time.
