Misaligned address for type 'double', in serialization.h, causing runtime error. about roscpp_core HOT 7 CLOSED

Could this be architecture specific?

Possibly.

I'm unable to reproduce this in melodic and looking at the serialization.h file it looks very different. I believe this code has been refactored and the issue got fixed indirectly by that.

This is an alignment issue, meaning that a variable is stored or accessed at an unaligned memory address. Correct C code should not store an 8 byte variable at a memory address not divisible by 8.

@zhoulaifu The line number in your error message doesn't match the current code in the repository. Please try to reproduce the problem with the latest code and comment if you are still seeing the problem and if yes, include updated information.

@hannob This repository uses the same branch for Kinetic as well as Melodic.

Which version of the repo and which distro would you want me to check? FYI, the error message above was from kinetic.

from roscpp_core.

As mentioned above: the line number in the error message doesn't match the code on the default branch so you might be using an older version. Please post the version number of the package you are using.

Please try to:

• update to the latest released Debian package or
• build the current HEAD of the default branch from source - that works either for Kinetic, (Lunar), or Melodic

The issue disappears when I have updated the package ros_kinetic_desktop_full to the latest version. Thank you, @dirk-thomas.
