sanitizer USE flag is glibs-specific, and cross-compiler for AVR uses dedicated avr-libc. It won't build with sanitizer USE flag (which is enabled by default). Logs from build are available in the gentoo forum's thread from URL section. I propose to remove sanitizer USE flag for gcc builds on AVR platform. Reproducible: Always
i'm pretty sure this was already done...
It was not working for me before explicitly disabling sanitizer flag in my package.use file. Is it because -S (stable) flag passed to cross-tools util? Let me know if this is not reproducible.
