>Description:
When compiling for PowerPC with following options
powerpc-gcc-3.2.2 -O -msoft-float -mstring -fforce-addr
and following C file with the below line
2
resulting "Internal compiler error"
Removing any of above switches the error does not occur.
>How-To-Repeat:
Build a powerpc cross compiler with above configuration
create a C file with "void prt(char *fmt,...) { }" line.
And compile it with above switches...
>Fix:
Sorry, unknown how the compiler works or if any of the compiler switches has any conflicts against each other.
