Follow-ups

--- Graf Yang 2009-08-03 03:25:05

I can not reproduce this bug. Vivi will try it again.

--- Vivi Li 2009-08-05 03:06:32

I can reproduce it on regression.

When stage is not cleaned after building bluetooth kernel, it will affect the

build of openobex and enable BLUETOOTH in openobex.

Please refer to the attached two config.log.

--- Graf Yang 2009-08-06 02:14:34

It is caused by stack overflow.

A uClibc variable __pagesize is overrided many times by the stack, then a cplb

error occured in __heap_free().

The flat format ircp will use 8k stack now.

--- Vivi Li 2009-08-10 06:10:23

OK now. Close it.
