[En-Nut-Discussion] WinAVR-20080411

[Ernst Stippl]

Hi!

A quick look into winavr_20080411 yielded:

an error message during the compilation of wlandrv.c saying 

"Wlandrv.c:1005: error: array subscript is above array bounds"

Goggling with "gcc 4.3.3 array subscript is above array bounds"

had a hit on: 

 http://gcc.gnu.org/gcc-4.3/changes.html : down the page it says:

-Warray-bounds has been added and is now enabled by default for -Wall . It
produces warnings for array subscripts that can be determined at compile
time to be always out of bounds. -Wno-array-bounds will disable the warning.



Line 1005 in wlandrv.c is a "memcpy" function call. Maybe the definitions of
the call parameters in line 872/873 have to do with the error. 


Regards
Ernst

I found that yesterday but hadn't investigated it much since I'm not using
either module.
It gave me an array indexing error in wlandrv.c on a line that didn't make
sense to me,
so I had only associated adc.c with that.
I was just working around those errors to get the rest of Nut to build.
