Analyzing Segmentation fault Core Dump (gdb)

Hi All,


I am getting following segmentation faults while running an Linux based application on imax6q custom hardware design. I back traced the core dump using Linux GDB and following you can see those core dumps. 


Kernel I'm using - Linux-boundary 4.1.15


Seg fault Core dump 1


Program terminated with signal SIGSEGV, Segmentation fault.
#0 gcoTEXTURE_BindTextureEx (Texture=0x263c6c4, Target=Target@entry=0, Sampler=1, Sampler@entry=0, Info=Info@entry=0x23f0708, textureLayer=textureLayer@entry=0)
at gc_hal_user_texture.c:3804
3804 gc_hal_user_texture.c: No such file or directory.


Seg fault Core dump 2


Program terminated with signal SIGSEGV, Segmentation fault.
#0 _SetFenceCtx (fence=0x5c30d6c, head=0x5c2ab74) at gc_hal_user_hardware.c:5752
5752 gc_hal_user_hardware.c: No such file or directory.


1) Those core dumps are directed to following source files. But I couldn't find those file in the above Linux-boundary 4.1.15 kernel build. What are they referring to ? To overcome with this problem what do you suggest ?







2) I could find a file called gc_hal_kernel_hardware.c in my kernel build. So is this the file the gdb back traced log is pointing out ? Do you have any idea of this kind of segmentation faults ?
