Chip Erase crashes program on WinXP and NodeMCU 0.9 board

[furyfire]

Running esptool.exe -cp COM9 -cd nodemcu -ce results Unhandled exception at 0x004013f2 in esptool.exe: 0xC0000005: Access violation reading location 0x00000000.

Does it happen with esptool 0.4.8 or 0.4.7? Initially 2.1.0 version of esp8266 core was distributed with 0.4.7, but a bug in esptool was fixed later on, now it ships with 0.4.8. Could you please run esptool -h and check?
