            Bug ID: 40132
           Summary: Categories in blacklist do not work
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: ubsan
          Assignee: unassignedbugs at nondot.org
          Reporter: antoshkka at gmail.com

We've attemted to manually run the misaligned test from
test/ubsan/TestCases/TypeCheck/misaligned.cpp with the following compiler
options `-fsanitize=undefined -fsanitize-blacklist=file.txt -O0 -g`.

Content of the file.txt is the following


The suppression did not work. Replacing =alignment with =undefined did not
help. Only removing the =alignment helped, which is not nice because we wished
to suppress only a single category of errors.
