Yeah, that one is unusual. Its probably another function, but DBX is reporting the wrong one. Have you tried turning knobs with your compiler settings? I'm not convinced Cmake provides good settings out of the box. -xmemalign looks like it may have some effect given the workarounds; see https://docs.oracle.com/cd/E19205-01/819-5265/bjavc/index.html. Be sure Cmake is not adjusting it to something that's not compatible. There's also a note in one of the old GCC manuals about using 8-byte alignment for SPARC; see https://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/Type-Attributes.html. However, its not present in the current manual. Jeff -- -- You received this message because you are subscribed to the "Crypto++ Users" Google Group.
