Question

I have a corruption memory heap problem with an application.
by using windbg and a dump file of the crash as an input I have the following output with dd esp command

0:002> dd esp
00000000`03e3e490  14badf55 00000000 03e3e8c0 00000000

00000000`03e3e500  00000000 00001000 78b83980 036b0000

There is this adress : 14badf55

I really don’t know how to interpret this “bad”..

Is anyone have an idea of the meaning of this bad ?

EDIT:

when I try to use this command :

 u 14badf55 

the following output comes :

00000000`14badf55 ??              ???
                ^ Memory access error in 'u 14badf55'

The .ecxr command give me :

Answer 1

You can see the c0000005 output in the file. This is the sign of a access violation.

Run the following:
– .cxr 00000000`03e3e4e0 (To set the exception context)
– kL (to get a stack trace)
