[BusyBox] Heisenbug

[Robert Schwebel]

Hi, 

I'm currently trying to compile busybox for an SA1110 based ARM system.
Compiling statically results in this error: 

----------8<----------
VFS: Mounted root (nfs filesystem).
change_root: old root has d_count=2
Mounted devfs on /dev
Trying to unmount old root ... okay
Freeing init memory: 56K
pc : [<00056fac>]    lr : [<000a6b4c>]    Not tainted

Control: C000F17F  Table: C000F17F  DAC: 00000015
----------8<----------

and so on and so on. So I thought it would be a good indea to compile
busybox with debugging and changed DODEBUG to 'true'. Result: it works: 

----------8<----------
VFS: Mounted root (nfs filesystem).
change_root: old root has d_count=2
Mounted devfs on /dev
Trying to unmount old root ... okay
Freeing init memory: 56K
init started:  BusyBox v0.61.pre (2002.08.30-17:30+0000) multi-call
binary
Bummer, could not run '/etc/init.d/rcS': No 
Please press Enter to activate this console.
----------8<----------

Can anybody give me a hint what I could to to track the problem down? I
suppose without debugging info in the binary it is a little bit
difficult to understand the objdump...

Robert
PS: busybox is latest CVS
