Description

« Hide

Repro: Put the attached script inside a prim and compile as a Mono script. I can't explain yet why it happens with this constellation but if, for example, the (unused) variable "intTest" is assigned a constant value, the exception is not thrown.

Observed: A script error with output similar to this:

System.NullReferenceException: Object reference not set to an instance of an object
at LSL_c2064255_b1ae_7db3_2e38_9caf1fbaf642.defaultstate_entry () [0x00000]
at LSL_c2064255_b1ae_7db3_2e38_9caf1fbaf642defaultstate_entryFrame.ResumeVoid () [0x00000]
at LindenLab.SecondLife.UThread.UThread.Run () [0x00000]
at LindenLab.SecondLife.Script.Run (ScriptEvent evt) [0x00000]

Expected: No script error.

Here is a more complicated script that produces the same error:

Can't reproduce with either script attached to this issue on server 1.24.3.95195 using client 1.21.0 (95157).

Cheiron, can you please attach the script that is causing the error?

No new info from Cheiron.

Ochi says it can't be reproduced.

I'm going to resolve this again.

Note: What Cheiron saw may one of the manifold hydra heads of the evil SVC-2908. I'll link that issue here
