All,
I need help in understadning Gdb stack trace:
[Switching to Thread 0xb73b4700 (LWP 28041)]
0x00000000 in ?? ()
(gdb) bt
#0 0x00000000 in ?? ()
#1 0xb5bfc9a6 in DefaultSerializeElementRule::serializeStart (this=0xa450e40,
domElement=0xa03e104, fd=0xa450ab0)
at /media/storage/working/content/serializer/src/DefaultSerializeElementRule.cpp:55
And here is my method:
void DefaultSerializeElementRule::serializeStart(nsIDOMElement*
domElement, FILE* fd) {
nsAutoString tagName;
domElement->GetTagName(tagName);
fprintf(fd, "<%s", NS_ConvertUTF16toUTF8(tagName).get());
// this is line 55:
serializeAttribute(domElement, fd);
}
I don't understand what is the meaning of :
0x00000000 in ?? ()
from the stack trace, both my domElement, fd are not null. So why my
program crashes?
Thank you.
