Getting LLVM error when building to device but not in simulator

When I attempt to build my test target to either my iPad1 (4.3.5) or iPhone4 (4.3.5) I'm getting the following error from Xcode 4 (Build 4A304a):

Internal compiler error: tree check: expected tree that contains 'decl with visibility' structure, have 'const_decl' in c_common_truthvalue_conversion

But not when the Test Target is switched to build in the simulator.

The line of code that is borking is

GHAssertNotNULL(xxxObject, @"xxxObject could not be 开发者_运维知识库created");

(objects have been renamed to protect the innocent ;-) ) But I can say it is a singleton.

I've search google and didnt get anything relevant for this error.

Thanking you in advance Ian.

I experienced the same compiler error:

internal compiler error: tree check: expected tree that contains 'decl with visibility' structure, have 'const_decl'  in c_common_truthvalue_conversion, at c-common.c:2836

Using Xcode 4.1 with GHUnitIOS-0.4.32 (and GHUnitIOS-0.4.31) when building for iOS devices. Note there is no issue when building for the simulator.

The complier errors involved calls to GHAssertNotEqualObjects and GHAssertNotEquals.

The code pattern that I was using when I received the compiler error was of the following:

- (void) test_isEqual {
    SomeObject *foo = [[SomeObject alloc] initWithValue: 1];
    SomeObject *bar = [[SomeObject alloc] initWithValue: 2];

    GHAssertNotEquals(bar, foo, @"Different Objects, different values - different pointers");
    GHAssertNotEqualObjects(bar, foo, @"Different Objects, different values - different pointers (calls isEqual)");
}

I was able to compile the code with the following modification:

- (void) test_isEqual {
    NSString *comment;
    SomeObject *foo = [[SomeObject alloc] initWithValue: 1];
    SomeObject *bar = [[SomeObject alloc] initWithValue: 2];

    comment = @"Different Objects, different values - different pointers";
    GHAssertNotEquals(bar, foo, comment);

    comment = @"Different Objects, different values - different pointers (calls isEqual)";
    GHAssertNotEqualObjects(bar, foo, comment);
}

Note that calls to GHAssertEqualObjects, GHAssertEqualStrings, GHAssertEquals, GHAssertFalse, GHAssertNil, GHAssertNotNil, and GHAssertTrue using a const NSString, i.e. @"some string", did not cause a compiler error.

Looking into #define GHAssertNotEquals(a1, a2, description, ...) and #define GHAssertEqualObjects(a1, a2, description, ...) and their use of description, both call GHComposeString(description, ##__VA_ARGS__), but so do the others macros that work.
