Make strcat() and strncat() more standard-compliant (check for invalid parameters even if zero bytes is copied, more accurate overlap check)
Fix the tests that were relying on the incorrect behavior.

Test that child threads use the ASan allocator, that allocated memory can be passed to another thread and deallocated on it.
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=81

Enable AddressSanitizerMac.CFAllocatorDefaultDoubleFree and AddressSanitizerMac.CFAllocatorMallocDoubleFree, which now work fine.

llvm-svn: 158886

Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

From now on we allow the clients to override signal handlers set by ASan, but print a warning in such a case.

Remove the tests for signal() and sigaction(), because they made little sense even without this change.

marked noreturn.

where memcpy() in fact aliases memmove() and thus calling it with
overlapping parameters is not an error.

This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=10

llvm-svn: 148696

Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10

[asan] workaround for bug http://llvm.org/bugs/show_bug.cgi?id=11763. Do not bark on memcpy(a, a, size).

AddressSanitizer: from this patch, ASan allocator returns false for __asan_get_ownership(NULL) and produce error reports for malloc_usable_size(NULL) and __asan_get_allocated_size(NULL)
