SAST / semgrep warning: "` was unexpected"

I have set up a SAST task in my .gitlab-ci.yml which executes successfully, but I see a lot of these warnings in the log:

` was unexpected

as in

//all the code from a source file
#endif
#endif /* __CORE_CM33_H_DEPENDANT */
#endif /* __CMSIS_GENERIC */
` was unexpected
[WARN] [Semgrep] [2024-11-27T18:07:19Z] ▶ tool notification warning: Syntax error Syntax error at line Drivers/CMSIS/Include/core_armv81mml.h:1:
 `/**************************************************************************//**
 * @file     core_armv81mml.h
 * @brief    CMSIS Armv8.1-M Mainline Core Peripheral Access Layer Header File
//code from the same file

so it complains about a ‘´’ appearing at the very beginning of a file, but the file does not actually contain this character at the beginning:

/**************************************************************************//**
