Re: Matlab 2020b crashes with labCA 3.7.2

Hi Till,

Thanks for having a look at this issue.

I was not precise with my description of the Matlab crash. We experience in the LBL rather deadlock ie. exactly what you have described. I do not have a log to show since Matlab "freezes" and there is no communication with it. 

There is an article below which shows the importance of Matlab and LabCA:

Hi Mirek.

Do you have any more information? Session logs? The more comprehensive the better
(please don't edit anything out).

I do have 2020b available here; everything builds fine but then refuses to load,
i.e., the first labca command hangs forever (without printing the initialization message).

I.e., I cannot reproduce a crash but rather experience a freeze or deadlock.

This happens also if I create a 'hello-world' style mex file and just link EPICS libCom
(ie., no labca at all).

Hello,

We are facing in the LBL a problem with Matlab 2020b crash when using labCa 3.7.2.

Has anybody else experienced the same problem?

It looks like the incompatibility between the Matlab 2020b and labCa latest official version.
