With the following change, traceback_t size changes from 24 bytes to 32 bytes:
diff --git a/Modules/_tracemalloc.c b/Modules/_tracemalloc.c

The following structure size is 24 bytes, so no change:
typedef struct {
Py_uhash_t hash;
short nframe;
short length;
frame_t frames[1];
} traceback_t;
The short approach is promising :-)
