Invalid __block type specifier behavior

[Midar]

Oh wow, this is bad. And while there is a test for __block, it is not thorough enough to catch this. Let me debug this and improve on the test.

Fixed.

One more problem I found.
Two different blocks, that's capture single __block variable, does not share value of that variable.
We have variable __block int i = 2;
If first block do some thing like this i--;
In the second block variable "i" is still equal 2

I cannot reproduce this. Can you check your on the latest version? There were two commits to fix this, maybe you only checked out the first?

The following code works for me:

#import <ObjFW/ObjFW.h>

typedef void (^voidblock)(void);

static OFArray*
test()
{
    __block double d = 0;
    voidblock block1 = Block_copy(^ {
        d++;
    });
    voidblock block2 = Block_copy(^ {
        of_log(@"%f", d);
    });
    return @[block1, block2];
}

int
main()
{
    OFArray <voidblock> *t = test();

    t[0]();
    t[1]();

    return 0;
}

Yes, it's work for now.
Tested build with latest changes.
Thanks.
