[Lldb-commits] [lldb] [lldb] Reduce output of TestDataFormatterStdVBool (PR #206444)

[Felipe de Azevedo Piovezan via lldb-commits]

Tests should not be printing an unbounded amount of data, especially when said data is the subject of corruption or misinterpretation by the printer (the formatter, in this case).

This test is currently failing on the matrix bots, with the result that close to 3GB of text is produced.

Subject: [PATCH] [lldb] Reduce output of TestDataFormatterStdVBool

Tests should not be printing an unbounded amount of data, especially
when said data is the subject of corruption or misinterpretation by the
printer (the formatter, in this case).

This test is currently failing on the matrix bots, with the result that
close to 3GB of text is produced.
