I am getting very frequent "Segmentation Faults" in a variety of projects. The solution that usually works is to clean the code or to simply move some code around, it usually compiles OK. That works most of the time, but not always.
There are always three error messages:
and this warning:
Is there something that causes these segmentation faults? Is there a compiler upgrade that will fix this problem?

I haven't seen error messages in that specific format before, but there is a known problem with the newest production version of avr-gcc provided by Arduino. Here is my standard response for this issue:
This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer. It has been reported here:

Hallo,
I have the following sporadic error. Memory is checked with Memtest an… d okay.
If I copy the sketch into a new window, no errors will occur.
With the older SD-Lib version of IDE 1.8.5 compiles without errors under the new IDE 1.8.6

```
Here's the traditional workaround:
Tools > Board > Boards Manager
Wait for downloads to finish.
When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
Click "Install".
Wait for installation to finish.
Click "Close".
Due to a bug , this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE.
If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.
Alternate workaround:
(In the Arduino IDE) File > Preferences
In the "Additional Boards Manager URLs" field, enter: http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json If you already have an additional Boards Manager URL in that field, you can separate multiple URLs with commas or click the button on the right side of the field to open a dialog that allows you to add each on its own line.
Click "OK"
Tools > Board > Boards Manager
Wait for the downloads to finish
Click on "Arduino AVR Boards by Arduino"
Click the "Update" button.
Wait for the update to finish.
Click "Close".
