Hello,
I have often a compiler internal error "Segmentation fault", specially when
my code contains loops (while, do while, for).
It seems to me that the compiler option -Wunreachable-code causes the error,
idenpendently of the option -O (I tried -O0 to -O3 and -Os, with indentical
result).
I don't know if it is a fault in my code (see below) or in the compiler.
Does anyone know where is the problem ?
Thank you.
Jean-Marc Michel
Detail
------
I use mspgcc-win32, version 20041112 (windows 2000 SP4).
Without option -Wunrechable-code
--------------------------------
Command line :
msp430-gcc -c -mmcu=msp430x149 -Os -g2 project.c
Result :
always ok.
With option -Wunrechable-code
-----------------------------
Command line :
msp430-gcc -c -mmcu=msp430x149 -Os -Wunreachable-code -g2 project.c
Result :
project.c: In function `fb':
project.c:20: internal error: Segmentation fault
