Xerces-C: Run Time Segmentation fault when fread is invoked

[Venkatesh Thanneermalai]

Hi Team,

I am using xerces 3.1.4. When the program is executed, the Initialize was
succesful and I had created an object for DOMParser on which I had called
parse() on an Input File in the local system.

While executing the same, got a segmentation fault




*Segmentation fault (protection violation) when writing to
0x1001002eb48Interrupt: 14Signal code: SEGV_ACCERR - Invalid permissions
for mapped object (2)A*borting process CBACsInstallerPT (15) in VM (id:0,
pid:8147, spawner pid:7788, lm set version:1)

Any help is appreciated on the reason.
