EXC_BAD_INSTURCTION (code=EXC_I386_INVOP,subcode=0x0) about amsmb2

[amosavian]

This is a bug in libsmb2. I'll made a workaround to fix this. Though I'm not sure it can be fixed as I can't reproduce it.

Thank you for your response, today also got one more crash. seems when we do some concurrency operations. we are getting crash issue.

Hi facing EXC_BAD_INSTURCTION crash sometimes. Please see the attached image.

I am also facing same kind of issue. Seems like issue in SMB library.

[amosavian]

It would be great if anyone can write a test case which reproduces this error.

[srinadh-k]

Here is my test case:

calling connectShare method every 30 seconds to establish or check Connection with "smb".
Our app runs 24*7 in background and foreground. So after couple of hours later we are getting crash.

[amosavian]

This is not a test case. A method must be added to https://github.com/amosavian/AMSMB2/blob/master/AMSMB2Tests/AMSMB2Tests.swift to replicate this issue

I finally found out that the problem is in smb2->outqueue, where pdu->cbdata is probably isoverreleased.

I will try to handle this.

Thank you
