Are you able to reproduce this in a sample app? I tried the following but got no crash: #include <stdio.h> #import <Foundation/Foundation.h> static void foo(NSString **fillMeIn) { [@[@"a"] enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { *fillMeIn = obj; *stop = YES; }]; } int main(int argc, char **argv) { @autoreleasepool { NSString *out; foo(&out); printf("%s", out.UTF8String); } return 0; } --Kyle _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
