rose_build_add.cpp: Potential Integer Overflow

[stasos24]

Since 'ig[e].graph_lag' and 'graph_max_width' have uint32 type

and 'graph_max_width' can have value :

(1u << 31) - 2; 

which is checked at

vectorscan/src/rose/rose_build_add.cpp

Line 899 in 4f09e78

if (!graph_max_width.is_finite()) {

there could be overflow at

vectorscan/src/rose/rose_build_add.cpp

Line 903 in 4f09e78

max_width = ig[e].graph_lag + graph_max_width;

'max_width' has u64 type
