[Oberon] FPGA - TRAP 4

[Tomas Kral]

Joerg, Michael,

Thank you this all helps.
I have not paid much attention to OBERON.FS until now.
When I broke it I just restored from the last copy.

Now with my minimal FS (provided is just right), this happens, and I can
reproduce it.

Fresh boot with a FS.
473 sectors used.

Last file copied Viewers.smb, which is correct, indeed was copied last during build.

I typed up MODULE Test; END Test. Make a few changes here and there.
I do not store the Test.Mod
ORP.Compile @ ==> I have a crash

Looking at the image, after 00085bb0 I can see dump of System.Log, as you explained earlier.
Taking up 2 sectors.

After reboot, sectors used 475, the two with unlinked System.Log not reclaimed.

When I do this exercise on the fresh FS again and store Test.Mod first
ORP.Compile @ ==> alright, no crash.

Any other modules, compiles on fly without saving, their store is reclaimed.

If I pressed ABORT button at the crash, the System.Log would take up 63 sectors, never reclaimed.
