Some years ago, I heard of a bug related to use of malloc. The
code had _intended_ to dynamically allocate storage for a string
and the terminating null byte. It was _intended_ to do this:
dest = malloc(strlen(src)+1);
Instead, a paren was misplaced:
dest = malloc(strlen(src))+1;
IIUC, the next line copied the src string into the newly-
allocated destination.
Those who had worked on that project longer said the bug had been
latent in the code for several years, most likely with alignment
padding masking the bug from being discovered. Curiously, the
bug made itself manifest immediately upon changing from a 32-bit
build environment to a 64-bit build environment.
