[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED CC| |[email protected] Resolution|--- |WORKSFORME --- Comment #4 from [email protected] --- gcc 4.2.1 doesn't complain when specifying C99 as the standard (-std=c99). In C89 (-std=c89) it (correctly) complains about "redeclaration of ‘i’ with no linkage", because in C89 the definitions in the first clause of a for statement are in the surrounding scope instead of the loop body's scope. clang also complains when using C89: % ~/LLVM/build/Release+Asserts/bin/clang -std=c89 clang.c clang.c:5:14: error: redefinition of 'i' for (int i = 0; i < 100; ++i) { } ^ clang.c:3:9: note: previous definition is here int i; ^ 1 error generated. I guess gcc and clang use different C standards as default, which is why you got the differing results. -- You are receiving this mail because: You are on the CC list for the bug.
