ESP32 reboots when enable SPI

While developing firmware we stumbled upon very strange behaviour. We have ESP32-WROVER with SPI chip MCP23S09 connected to it. But after trying to initialize SPI, ESP32 reboots. Interesting thing is that if we use ESP32-WROOM, then this problem does not happen. Here is sample application (can use d...
