Raspberry Pi OS, malloc() when running script

[FlorSanders]

• Version: 14.7.0
• Platform: Raspberry Pi OS (32-bit) Lite
• Subsystem: Debian Buster

What steps will reproduce the bug?

Running the program included in the RMLMapper subfolder of this repo I'm working on, causes the following output on Raspberry Pi OS (Debian Buster):

node index.mjs
malloc(): invalid size (unsorted)
Aborted

This doesn't happen when running on windows.
All necessary dependencies are installed through npm and node does run when starting node through the command line.

How often does it reproduce? Is there a required condition?

Any time I start the program on the raspberry pi.

What is the expected behavior?

The expected behavior is for the program to start running.

What do you see instead?

As already mentioned:

node index.mjs
malloc(): invalid size (unsorted)
Aborted

Additional information

Since only a malloc() error is thrown with no further information I suppose it has something to do with the node environment itself, though I'm not sure. In any case there's too little information here for me to debug it on my own.
Any help that might resolve this issue would be really appreciated.

What does find node_modules/ -name \*.node print? What happens when you run node under gdb? (gdb --args node index.mjs, then r to start the program and bt to print a stack trace after it aborts.)

[FlorSanders]

find node_modules/ -name \*.node prints the following:

node_modules/xpath-iterator/build/Release/obj.target/xpathWrapper.node
node_modules/xpath-iterator/build/Release/xpathWrapper.node

Running node under gdb yields the following results:

Try excluding that xpath-iterator module, just in case.

If that doesn't fix it, please report your issue to whoever provided you with the binary (debian?) because I can tell from the fact that it's linked to /usr/lib/arm-linux-gnueabihf/libnode.so.64 that it isn't an official binary from https://nodejs.org/.

I'm going to close this but I can move it to nodejs/help if you have follow-up questions.

Thanks for pointing out that it had nothing to do with the node.js core.
I had installed node.js and npm through nvm, which apparently was the cause of the issue.
After uninstalling that and installing the latest stable release from the nodejs.org website everything runs fine.
My bad. Really appreciate the help!
