             Summary: Cocoa code generator emits reserved symbol, 'i386'
                 Key: THRIFT-2676
                 URL: https://issues.apache.org/jira/browse/THRIFT-2676
             Project: Thrift
          Issue Type: Bug
          Components: Cocoa - Compiler
         Environment: Xcode 5 (iOS)
Xcode 6 (iOS)
            Reporter: Keith Lazuka


The Cocoa code generator has a bug where it can generate a local variable that conflicts with a symbol defined in the iOS SDK. Specifically, it happens when the temporary variable counter reaches the value `386` when emitting an index variable for a for-loop in `t_cocoa_generator::generate_serialize_container()`. The offending symbol is `i386` which apparently is #define'd to equal `1` somewhere in the iOS toolchain.

This test code demonstrates the problem, regardless of Thrift codegen.

{noformat}
    int i386 = 42;
    printf("foobar %d\n", i386);
{noformat}

Which results in the following compiler error:

{noformat}
/Users/keith/Desktop/ReservedSymbolTest/ReservedSymbolTest/ViewController.m:22:7: error: expected identifier or '('
  int i386 = 42;
      ^
<built-in>:143:14: note: expanded from here
             ^
1 error generated.
