Line 75 in string_32.h is part of the __constant_memcpy() function. That function should not be involved here because the length argument isn't a compile-time constant. This has to be either a compiler bug or else a bug in the implementation of memcpy. Alan Stern ^ permalink raw reply [flat|nested] 2+ messages in thread
