            Bug ID: 45424
           Summary: Strange reformating if lambda as argument has other
                    arguments before and after it.
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: stayprivate at gmail.com

Before 

void testing()
{
        foo(10, []() { fun(); });
        foo(20, []() { fun(); }, "abc");
        foo([]() { fun(); });
        foo([]() { fun(); }, "abc");
}

After

void testing()
{
        foo(10, []() { fun(); });
        foo(
                20, []() { fun(); }, "abc");
        foo([]() { fun(); });
        foo([]() { fun(); }, "abc");
}

Notice only the line with arguments before and after the lambda was reformated
on two lines. With latest clang-11 but does it with clang-10 as well.


Below is my .clang-format
