Getting Segmentation Fault on 1.31

[Zorro666]

Hi. It sounds like something changed on your system if v1.30 was working and then it stopped working. Was there a driver update or system updates.

Without more details on the crash then not sure how to help.

If you can make a debug build and run the executable in a debugger that would be helpful

[P-S-Y-S-U]

oh okay. i will check it out

[P-S-Y-S-U]

ok i tried debugging the renderdoccmd target.
i get seg fault at renderdoc/os/posix/linux/linux_hook.cpp at line 69.

On this line
DLOPENPROC passthru = (DLOPENPROC)dlsym(RTLD_NEXT, "dlopen");

[Zorro666]

Can I clarify a few things.

• have you downloaded and built renderdoc from source?
• can you share a callstack (back trace) when the crash happens?
• what command line did you use to launch the program?

If you run the RenderDoc "qrenderdoc" from the command line what happens?
If you run the internal program "renderdoccmd" from the command line what happens?

Do you have any environment variables set that are related to library loading i.e. LD_* variables

[P-S-Y-S-U]

have you downloaded and built renderdoc from source?

yes

can you share a callstack (back trace) when the crash happens?

what command line did you use to launch the program?

just launched both programs without any command-line args

If you run the RenderDoc "qrenderdoc" from the command line what happens?
If you run the internal program "renderdoccmd" from the command line what happens?

Do you have any environment variables set that are related to library loading i.e. LD_* variables

Nope

[Zorro666]

It looks like this might be the issue

/usr/local/lib/AppProtection/libAppProtection.so

Can you uninstall the Citrix App Protection? or it looks like deleting "libAppProtection.so" will fix it (I would copy it and rename as a backup in case you do need it in the future).

There are reports that it causes problems

Yup that's the culprit.
thanks it works now.
