Bug ID: 117124
   Summary: Header file contents get modified when macro defined
before header file inclusion
   Product: gcc
   Version: 11.4.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: preprocessor
  Assignee: unassigned at gcc dot gnu.org
  Reporter: akhil.k.joyson at gmail dot com
  Target Milestone: ---

Also try with custom header

Hi team,

If I #define with any macro which is also available in the header files, then
the header file data is also getting changed/corrupted. I was not expecting the
header file content to be modified since the header file is either from std lib
or user-defined lib.

Please check into this issue.
If required I can explain with further Images/explanations.

Regards,
Akhil

Preprocessor throwing error only when the Terminating comment in missing.

Hi team,

Expecting error similarly when there is no terminating comment present and only
staring comment present.

Thanks and regards,
