That's news to me. Then I googled it. You're right. >From >https://wiki.sei.cmu.edu/confluence/display/c/EXP36-C.+Do+not+cast+pointers+into+more+strictly+aligned+pointer+types
The C Standard, 6.3.2.3, paragraph 7 [ISO/IEC 9899:2011], states A pointer to an object or incomplete type may be converted to a pointer to a different object or incomplete type. If the resulting pointer is not correctly aligned for the referenced type, the behavior is undefined.
