CC Mode 5.33.2 (C++//l); CC-mode inconsistently indents everything as topmost-intro after a while |

This seems related to (if not the same as) bug #5490.
- This happens randomly and then randomly stops happening (cache expiry maybe?)
- M-x revert-buffer does not fix.
Here's a snippet from the buffer at the time this happen, as you can see
there seems to be a region until the end where everything becomes
topmost-intro:
} // ((block-close 18328))
// ((statement 9560))
SDL_DestroyWindow(Window); // ((statement 9560))
} // ((block-close 9490))
else // ((else-clause 9466))
{ // ((substatement-open 18464))
PlatformLog("Failed to create window: %s", SDL_GetError()); // ((statement-block-intro 18473))
} // ((block-close 18473))
// ((topmost-intro 18576))
// ((topmost-intro 18576))
SDL_Quit(); // ((topmost-intro 18541))
} // ((topmost-intro 18548))
else // ((else-clause 9188))
{ // ((substatement-open 18845))
PlatformLog("Failed to initialize SDL: %s", SDL_GetError()); // ((statement-block-intro 18901))((statement-block-intro 18724))
} // ((block-close 18901))
// ((topmost-intro 19093))
return EXIT_SUCCESS; // ((topmost-intro 19093))
} // ((topmost-intro 19242))

OK, thanks for the test. I think it is now time to commit the patch and
close the bug.
I am hoping that the patch, already applied to the savannah master
branch, will also have fixed bugs #5910 and #18072. Their (sporadic)
symptoms were consistent with the glitches fixed by the patch.
