I'm new to writing tests for header files. I got the following error. Is there
a suggestion for this? Thanks!

Input was:
<<<<<<
1: 1 warning generated.
check:5'0 X~~~~~~~~~~~~~~~~~~~~ error: no match found
check:5'1 with "@LINE-1" equal to "4"
2: Suppressed 1 warnings (1 in non-user code).
check:5'0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
check:5'2 ? possible intended
match
3: Use -header-filter=.* to display errors from all non-system
headers. Use -system-headers to display errors from system headers as well.
