<![CDATA[Qt5 segmentation fault with libEGL.so.1 lib]]>Hi team,

I am using the Qt5.15.2, there i trying to run the qt5/exmaples/gui/openglwindows application but getting the segmentation fault. Below is the bt of gdb .

ype "apropos word" to search for commands related to "word"...

I am suspecting on libEGL issue somewhere. I have been stuck on this issue since very long time.
Please help me on this issue.

That one has a debug package.

I am suspecting that there is no debug package available for library libEGL.

If you have any information on this, then please suggest the concern library for libEGL seg fault and better place to debug GDB/Qt creator?

libegl-dev

This is development package containing header files, not debug package of the library.

You mean the dbugging package of libEGL ? I think i have the libegl-dev package.

how to debug this seg fault issue , In Qt or using GDB . GDB is getting stopped at Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)

How to process further here , Please suggest on this .

You should install the debugging packages for these libraries. That should give you better information for your stack strace.
