Fatal Internal Error: "objheap.cpp", line 541

[alexphysiker]

Hello guys,

I've got the following problem:

I can open my main.vi, but if I do some changes and try to save the vi I get in the error in objheap.cpp, line 541.

I've found this old interesting post

http://forums.ni.com/t5/LabVIEW/Objheap-cpp-error-in-6-0-2/m-p/162830

Robert describes that it could be the problem with the type descriptor.

I wanted to ask, if this problem has been solved in the later LV-versions?

It could be the reason of the error, because we have a big main.vi (about 1200 KB) with many small SubVis (about 150 VIs).

Do you have any idea about this error and a tip for me, what could I do with it?

We have:

LV 10.0 f4

Windows XP Professional (version 5.1, Service Pack 3).

Thank you.

Hi alexphysiker

I have looked into this error and it is a known error in LabVIEW and has a corrective action request number 249309 and hence National Instruments R&D department aware of the problem.

Have you tried copying the contents of the one VI which courses the error into an blank VI then save the VI.

Is there a specific set of conditions that course the crash to accrue?

Hallo Robert,

The error occurred when I tried to copy and paste one (small) part of the code (after the program or I tried to saved the VI).

I could not really solve this problem and uploaded the previous version of the VI, now I don't get this error (althought I've done the same changes like in the version of VI with the error).

It is not the best solution, but I can work again on the VI.

But I'm very interesting to know the reason for this error.

Cheers: Alex

Hi Alex

R&D is investigating the issue and so at present I do not have access to what is the course of the error.  

In future releases of LabVIEW in the read me it will quote all of the corrective action requests (CARs) that have been resolved in that release.

It is good to hear that you have found a work around and that it is not coursing you continued issues.
