It only happens when using the experimental FORTIFY_SOURCE support [1],
and it only happens with gcc (the base one is the only tested).
Yes, I am suspecting a compiler bug but gcc has been really useful to
find
bugs in fortify_source.
gcc is correct. This has nothing to do with 'const'. aHdr has a
volatile qualifier.
OK, I am testing the patch for this. Thanks!
Pedro.
