Description :
The program below should probably be rejected as ill-typed:
main(){ int foo, x, y; foo ? (void)x : (signed char)y; return 0; }
but:
$ ppc/bin/toplevel.opt -val t.c [kernel] preprocessing with "gcc -C -E -I. t.c" ... [value] Values at end of function main: __retres ? {0}
Incidentally, for this example, the access to uninitialized variable foo should also cause the program to be analyzed as non-terminating. Not sure whether that secondary bug is in the front-end or in the value analysis.
