A V061 message indicates that an error related to the analyzer's functioning has occurred. It could be an unexpected exception in the analyzer, failure to build a semantic model of the program, and so on.
In this case, please email us (email@example.com) and attach the text files from the .PVS-Studio directory (you can find them in the project directory) so that we could fix the bug as soon as possible.
In addition, you can use the verbose parameter to tell the analyzer to save additional information to the .PVS-Studio directory while running. That information could also be helpful.
verbose = true
IntelliJ IDEA plugin:
1) Analyze -> PVS-Studio -> Settings
2) Tab Misc -> uncheck Remove intermediate files
