Can this related to endianness? Based on current reports, it only occurs on big-endian platforms.
I found: * Note: in order to use the optimized macros your platform must support unaligned 32 and 64 bit read/writes. * The x86 platforms allow this but some others [ARM for instance] do not. On those platforms you **MUST** * use the portable [slower] macros. in https://github.com/mkj/dropbear/blob/master/libtomcrypt/src/headers/tomcrypt_cfg.h A quick way to verify this might be define LTC_NO_ASM.
