--text follows this line--
Editing a C header file and trying to add a doxygen-style comment.  Itried to enter an open parenthesis in the comment and emacs hangs.  Iwas able to replicate this multiple times.  I was able to narrow it downto these lines being present in the file:
/* make sure LogStorageTable_t is packed */COMPILE_TIME_ASSERT(sizeof(LogStorageTable_t) == ((sizeof(LogStorageArea_t) *                                                   LOG_STORAGE_NUM) +                                                  sizeof(uint16_t)));
/** hang if open parenthesis is pressed here -> 
Entering a open parenthesis in the above line causes emacs to hang.  Isent signal USR2 to the process and got the attached screen shot (sorry,couldn't cut and paste from the emacs window after the hang).

(This bug report unfortunately got no response at the time.)

I tried reproducing this in Emacs 27 (and 28), and I was unable to.  Do
you still see this bug in Emacs 27?

More information was requested, but no response was given within a 
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
