Description

Activating a 'for i' code completion template and pressing CTRL-T 5 times, produces an Access Violation in the IDE and crashes it.

CTRL-T is removing the word at the cursor (standard keymapping)

I've tried this without any add-ons in the IDE.

Steps to Reproduce:

1. Start Delphi
2. File / New VCL form
3. Double click on the form to get to the FormCreate
4. Write the following 5 characters: for i
5. Press CTRL-T 5 times. The 5th time, the IDE crashes on an Access Violation at address 206BF5C3 in module 'coreide160.bpl'. Read of address 00000000

This is the resulting callstack:
