7 years ago I wouldn't expect crashes using my code with 50Hz. You would just loose some dimming at low brightness. I would expect the dimming range to be something like 20-100% (it likely wouldn't even be noticeable). Do you crash when you're at 100% brightness?
My code will delay for a max of 8050us (8.3ms in a half-wave for 60hz). I would try something like 'int dimDelay = 37 * (255 - curBrightness) + 500;' for 50hz. That would give you a max delay of 9935us (10ms in a half-wave for 50hz), which is close enough.
Make sure your buttonType and buttonActiveOn is set correctly. It doesn't seem like it would cause crashing, but if these are not set correctly, it may thing the button is being held down.
Also, Make sure you using a newer version of the ESP Arduino library. Using an older version will cause WDT crashes before they corrected the NMI timer bug. I'm currently using Arduino 1.6.9 w/ esp8266 v2.3.0-rc2.

I am using your code for 220V 50Hz but esp8266 resets any time, I tried to change hw_timer_arm(dimDelay); value by hit and trial but of no use , can you please help me to calculate it for 50Hz. Best Regards.
