ValueError: invalid literal for int() raised from yaml.load

[gabe-sherman]

The below code results in a ValueError when yaml.load is called. I wanted to report this since it seems that when data is malformed, ConstructorErrors are typically raised. This occurs in the function construct_yaml_int at line 250 in constructor.py.

Minimized Reproducer:

import yaml
yaml.load("0x_", Loader=yaml.FullLoader)

Version Information:

7.0.0.dev0 also occurs in the current release: 6.0.2

Exception Trace:
