Call stack :

[dodikk]

Using NSString instead of NSNumber works

As is

    dict[@"1"] = @1;
    dict[@"2"] = @2;
    dict[@"3"] = @3;
// This crashes

To be

    NSDictionary *patternDict = @{
    @"1" : @"111",
    @"2" : @"222",
    @"3" : @"333",
    }; // this works

[dodikk]

The same architecture set must be used both for the library and the test target

[dodikk]

Still reproduces.
Does not help.

[dodikk]

Probably, tagged pointers may be the cause

[dodikk]

Confirmed : tagged pointers are the cause.
