Bug ID: 27131
Summary: -Wincompatible-pointer-types treats constnat strings
as NSString even when -fconstant-string-class is used
Product: clang
Version: unspecified
Hardware: PC
OS: FreeBSD
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: [email protected]

Classification: Unclassified
When using an alternative class for constant strings (i.e. I am not using OS X
or GNUStep ) then warning for incompatible types are generated, which appear to
be based on still using NSString as the class of the constant string. For
example this code:
MyConstStr *s;
s = @"foo";
will generate this error
test.m:21:7: warning: incompatible pointer types assigning to 'MyConstStr *'
from 'NSString *' [-Wincompatible-pointer-types]
s = @"foo";
This works fine under gcc 4 and 5. Note that the resulting code works fine, it
is just the warning which is wrong.
