+a matrix for you. You don't need to pass identity matrix.

+you didn't have any existing matrix you have to initialize matrix to identity
+before sending to transfrom functions.

+
+This is similar issue with alignment. For instance if you compiled **cglm** with 
+AVX (**-mavx**, intentionally or not) and if you use **cglm** in an environment that doesn't 
+support AVX (or if AVX is disabled intentionally) e.g. environment that max support SSE2/3/4,

+
+Because if you compile **cglm** with AVX it aligns **mat4** with 32 byte boundary, 
+and your project aligns that as 16 byte boundary...
+
+Check alignment, supported vector extension or simd in **cglm** and linked projects...
