segmentation fault in Labview 7.1.1 for Linux (RH9)

[alexbilo]

Hi,

I work on a quite big application that runs on a Red Hat 9.0 Linux machine.

I get a SIGSEGV that kills my application from time to time :

LabVIEW caught fatal signal

7.1.1 - Received SIGSEGV

Reason: address not mapped to object

Attempt to reference address: 0x22

Segmentation fault

I'd like to know how am I supposed to troubleshoot that error, I don't have a clue...

I saw a few posts about issues with Fedora Core distributions, but they don't apply to me.

Any idea?

Thanks a lot,

Alex

Isn't there a way to edit posts?

Some additional information:

The problem seems to disapear when I remove my serial ports aliases in visaconf.ini, which means two things :

1) The serial ports (there's four of them) are not initialized anymore

2) The application continously communicate with a serial instruments on COM1 - that communication is obviously broken... We manage these errors so nothing wrong happens

BTW, the problem occurs only at run-time, wheter I run the application as a VI or as a built executable

Thanks,

Alex

Did the .ini edit solve the problem?

I just upgraded from 8.2 to 8.5 and now have SIGSEGV fatal errors.

Hi Alex,

Are you using a 32-bit or 64-bit machine?  This segmentation fault error will occur if trying to install LabVIEW for Linux on a 64-bit machine.  If you are using a 32-bit machine, the following article lists steps on how to resolve this error so that you will immediately be able to use LabVIEW.  Hope this helps!

Why Do I Get Segmentation Fault Errors When Installing LabVIEW 7.1 and Earlier on Linux?
