I am having the exact same issue in the Hind all of the sudden tonight -- not sure what started causing it. Petrovich seems to cause a CTD after the second or third search command, I've already hit it to send the crash report a couple times.
Here's exactly what I'm doing
Starting at At Tanf in Syria Takeoff from Ramp at night with a Ukranian Mi-24, 8x ATGM and 2x20x 80mm illum rockets
Target range about 3km north of At Tanf, all Algerian (neutral, not set to red or blue) static objects: 2x T-72, 3x BTR-80, 3x BMP-1, 4x Ural 4320T, 4x technical with Dishkas
I am usually able to get a spiral on the first target with Petrovich, but the second or third search results in a CTD. I made sure my brakes aren't mapped to W (read the comments above) and also tried with wheel brakes on and off during attack runs -- CTDs happened either way.
