Public bug reported:
These are the errors made by the compiler.
/usr/lib/gcc-cross/arm-linux-gnueabi/9/../../../../arm-linux-gnueabi/bin/ld:

This is the compilation command:
arm-linux-gnueabi-gcc ./main.c -s -static -pthread -O3 -flto -std=gnu11
-DNDEBUG -Wall -Wextra -lm -march=armv7-a -mfpu=neon -mfloat-abi=softfp -DNEON
-o ./Prova_linuxarmv7 -fprofile-generate -lgcov
The same command without "-fprofile-generate -lgcov" works well.
