Public bug reported:
Binary package hint: gcc-avr
Hi,
gcc-Version 4.3.5 (GCC), AMD64 default Maverick package.
The attached source file (see also the preprocessed input) yields corrupted
machine code:
The short example "control_unit.c" contains a single for(i=0; i<6; i++)-loop
that is supposed to run exactly six times.
Instead, the compiler produces a loop with undetermined behaviour that runs
tens of times at least.
I compiled with the following command line for target ATTiny26:
avr-gcc -v -save-temps -c -std=c99 -g -Os -Wall -Wstrict-prototypes -Wextra
-Wa,-ahlms=control_unit.lst -mmcu=attiny26 control_unit.c
I've also attached the messages displayed during the above compile run
in the file "stdout-compile-messages.txt"
That file also contains the GCC options with which GCC for the AVR
target was configured.
Regards,
Ulrich
