Opening a port does not work with versions > 7.0.1 : segfault (MacOS & Ubuntu)

[pierreroth64]

Opening a port does not work anymore on my MacOS with versions > 7.0.1.

I created a repo with all the informations: https://github.com/pierreroth64/serialport-test

Do not hesitate to ask for more details if needed.

Thanks for your help

@pierreroth64 Have you tried the latest release of serialport@7.1.2 to see if the issue is resolved there?

I am seeing a segfault when trying to open port with the following:

• serialport@7.1.2
• Node v10.8.0
• Ubuntu 18.04 LTS.

Segfault on trying serialport@7.0.1 as well.
Same code works fine using serialport@6.2.2.

@kjhe11e Is this with any port or a specific device?

[kjhe11e]

@HipsterBrown
I only have access to one specific hardware device at the moment. It automatically connects to ttyUSB0.
Will test with some different hardware as soon as I can, hopefully in next few days.

We can confirm the issue with Arduino (/dev/ttyACM0) and CP210 hardware (/dev/ttyUSB0) serial port on Ubuntu 18.04 with nodejs 10.14.1 serial port module version 7.1.2 and 7.0.2, moving to 6.2.2 has solved the problem for now.

using https://github.com/ddopson/node-segfault-handler i get:

/serialport/node_modules/@serialport/bindings/build/Release/bindings.node(_Z5setupiP9OpenBaton+0x205)[0x7f631dcc9e15]
/serialport/node_modules/@serialport/bindings/build/Release/bindings.node(_Z8EIO_OpenP9uv_work_s+0x38)[0x7f631dcca078]

does that mean anything to you?

Hi, sorry for the delayed answer. Yes, it still does not work with serialport@7.1.2. Tried on several ports on my MacBook, for two various connected devices => calling port.open() results in a segmentation fault.
For all of those hardware configurations (ports and connected devices), serialport@6.2.2 works fine.

Same issue with 7.1.2. Latest MacOS + PL2303 TTL-to-USB adapter. 6.2.2 works fine.

#1772 should fix this once it lands

I've pulled the bad releases, sorry for issues everyone. It's been hard to test with hardware on all the platforms, so I really thank you for these bug reports.

Does 7.1.0 work for everyone?

[JBtje]

I had this problem this morning, and set @serialport/bindings to 2.0.3, which fixed the problem. If serialport 7.1.0 uses @serialport/bindings 2.0.3, it should work...

[Holger-Will]

7.1.0 still segfaults for me :-(

[Holger-Will]

to add to that, 7.1.0 still comes with binding 2.0.5.

[maxwellhadley]

7.1.0 still segfaults here, running macOS 10.13.6

I am happy to say serialport@7.1.3 has been released which fixes this issue.
