The text was updated successfully, but these errors were encountered:
While fuzzing boolector,
this input file
was found, which leads to a use after free in get_failed_assumptions.
The input file looks like this is related to #28, but the backtrace produced by ASAN is different, which is why this is filed as a separate issue.
The attached file contains more lines leading to the same crash, the above file contains the minimal version.
