Segmentation fault

[rei-vilo]

I'm trying to run an application built with RasPiArduino.

Summary of results

• Launched directly: throws Segmentation fault
• Launched with gdb: runs successful
• Launched with gdbserver: runs successful
• Launched with valgrind --leak-check=yes: reports many error messages

I've already checked https://stackoverflow.com/questions/59506152/valgrind-reports-hundreds-of-errors-in-hello-world-program-on-raspberrypi-4b about the messages from Valgrind.

The same application built with GDB enabled no longer raises the Segmentation fault error, but weights 4MB instead of 120KB.

Is there something wrong with the GDB disabled option?

Thank you for your help!

Configuration

• Raspberry Pi 3B
• Raspbian GNU/Linux 10 (buster)
• Arduino 1.8.13
• Valgrind-3.7.0

Although not very pretty, adding -fno-exceptions solved the issue.

Digging into the code to find the cause of the segmentation fault would be better.
