Regular expression search causes VS Code window to hang

[langton]

Issue Type: Bug

Step 1:
Create file with the following contents and save as foo.c. (Does not matter whether C extension is installed):

void function()
{
  int x;
                    /* Multi
                       Line
                       Comment */


                       
  return;
}

Step 2: Perform a regular expression search for /\*(.*\n?)*\*/ (outer backticks for markdown only).

Step 3: VS Code window will hang while regex is being typed/pasted and need to be reloaded.

Tested on Linux and Mac, with and without the C extension installed.

/duplicate of #30874

Problem is in (.*\n?) which is basically similar to (.*)*. You should make it more strict match instead of .* or remove repetitions
