Clang warns for this in the FE without any optimization:
gcc.dg/uninit-pr19430.c:10:7: warning: variable 'j' is used uninitialized
whenever 'if' condition is false [-Wsometimes-uninitialized]
if (bar (i)) {
^~~~~~~
gcc.dg/uninit-pr19430.c:15:10: note: uninitialized use occurs here
return j;
^
gcc.dg/uninit-pr19430.c:10:3: note: remove the 'if' if its condition is always
true
if (bar (i)) {
^~~~~~~~~~~~~
gcc.dg/uninit-pr19430.c:8:8: note: initialize the variable 'j' to silence this
warning
int j; /* { dg-warning "'j' may be used uninitialized in this function"
"uninitialized" { xfail *-*-* } 8 } */
