analyzer: bulletproof binop_svalue::maybe_get_value_range_1
Adds a type check to prevent crashes in the static analyzer when handling binary operations.
This commit adds a check for incompatible types in binop_svalue::maybe_get_value_range_1 to prevent potential crashes in the static analyzer. This is a defensive change that ensures the analyzer handles potentially malformed intermediate representations gracefully, preventing unexpected termination and improving robustness.
In Details
Similar to the fix for unary operations (r16-7560-gf310e487e1a5f0), this commit adds a type check to binop_svalue::maybe_get_value_range_1 to handle cases where the analyzer encounters incompatible types during binary operations. This prevents potential crashes due to unexpected data types in the intermediate representation.
For Context
A static analyzer is a tool that automatically examines source code to identify potential bugs and vulnerabilities. During its analysis, the analyzer performs various operations on the code's internal representation. This commit makes the analyzer more robust by adding a check to ensure that certain operations are only performed on compatible data types, preventing crashes and improving overall stability.
