--- Comment #8 from Sumit <sbansal at ciena dot com> --- Hi Segher, I somehow missed the below update from your side. Can you help me understand if this was some known issue in GCC which got fixed in r205896? If yes, can you let us know if got fixed in 4.8.1 version? Thanks.

This was fixed in 2013, in r205896 -- so should be fixed in 4.9 already. That commit added this to the documentation: In some cases, such as when the 'packed' attribute is applied to a structure field, it may not be possible to access the field with a single read or write that is correctly aligned for the target machine. In this case GCC falls back to generating multiple accesses rather than code that will fault or truncate the result at run time. (and also added the code to implement it; as you noticed, older compilers will do misaligned loads if you're not careful). -- You are receiving this mail because: You reported the bug.
