Summary: 2.9.0 pointer of pointer bug

Initial Comment:
Hi,
2.9.0 ( maybe version greater than 2.5.0) has bug !!
FreeRTOS on 8051 platform file list.c 
function void vListInsertEnd( xList *pxList, xListItem *pxNextListItem)

pxIndex->pxNext->pxPrevious = (volatile xListItem *) pxNewListItem;

I guess pointer of pointer access has bug.

FreeRTOS (6.0.4) is successfully compiled and run OK wit sdcc 2.5.0.
but with 2.9.0 , it fail to run.
compile option :
 --less-pedantic --xram-size 4096 --no-peep --int-long-reent --float-reent --stack-auto --data-loc 0x8 --iram-size 0x80

IckSeong, Jeon

I've compiled FreeRTOS 6.0.5 with a recent SDCC snapshot and it compiled
without errors.

Message:
Without all included header files it is impossible to reproduce this bug.
You could try again with sdcc -E > list.i and attach that file.
Please also try with the latest snapshot (2.9.7) as it may already be
fixed.
