Bug#977021: bus errors on armhf running on a 64bit kernel

[Bernd Rinn]

Dear Pierre,




- JDK 11 instead of JDK 8
- 64bit OS instead of 32 bit OS



All the best,
Bernd

No, I've not yet seen this bus error. I can see two changes to my test setup: The 64bit platoform is more likely to be the change that uncovers this bug. Which hardware did you get the error on?

Dear Bernd,



Have you already met this issue and do you see how it might be fixed?

Thanks a lot,
Pierre Gruet

In Debian we have received a bug report you may find below: there seems to be an unaligned memory access in (seemingly) the JNI part of sis-base version 18.09, leading to a failure on the architecture armhf running on a 64bit kernel. > building libsis-base-java (or running the jni) leads to a bus error, usually > LC_ALL=C java -Djava.library.path=source/c/.libs -classpath sis-base-test.jar
