Nios Eclipse crashes, free(): invalid pointer

[SThor8]

Hi

When starting nios ii from quartus the eclipse splash screen appear a short moment and then nothing happend.

Starting eclipse from the prompt result in the following error message

> ~/intelFPGA/20.1/nios2eds/bin$ ./eclipse-nios2 
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
free(): invalid pointer

Why the error message "free(): invalid pointer"?

Is it possible to get more information to trying trace the error?

Is there a fix?

The following workaround seems to work, it essentially replace Quartus included java engine with Java 8

cd ..../intelFPGA/20.1/quartus/linux64
mv jre64 jre64_old
ln -s /lib/jvm/java-1.8.0-openjdk-amd64/jre jre64

the path to Java 8 jre might be machine specific, mine is at least placed there
