Error messages are detected and parsed using a regex. Part of this regex matches the optional column number. The code that handled this assumed that a missing column would result in less elements in the matches array, but a regex always results in one element per set of parenthesis in the regex, which will be null if no capture was made for that element. In practice, this meant that if no column was present in the error message, a NullPointerException would be raised. Furthermore, gcc 9 seems to have started outputting omitting column numbers (instead of printing 0) for some errors (such as unterminated #ifdef), which exposed this problem. This commit fixes this by simply using the fixed match numbers to take apart the regex match, and by checking for a null column number (all other captures are non-optional, so no need to check there).
Arduino is an open-source physical computing platform based on a simple I/O board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing and MaxMSP). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free at https://arduino.cc

Bug reports and technical discussions
-
To report a bug in the software or to request a simple enhancement go to Github Issues
-
More complex requests and technical discussion should go on the Arduino Developers mailing list
-
If you're interested in modifying or extending the Arduino software, we strongly suggest discussing your ideas on the Developers mailing list before starting to work on them. That way you can coordinate with the Arduino Team and others, giving your work a higher chance of being integrated into the official release
Installation
Detailed instructions for installation in popular operating systems can be found at:
- Linux (see also the Arduino playground)
- macOS
- Windows
Credits
Arduino is an open source project, supported by many.
The Arduino team is composed of Massimo Banzi, David Cuartielles, Tom Igoe and David A. Mellis.
Arduino uses GNU avr-gcc toolchain, GCC ARM Embedded toolchain, avr-libc, avrdude, bossac, openOCD and code from Processing and Wiring.
