[DUG] Determine line number from MAP file

[Ross Levis]

Thanks Cheng.  I suspect Windows changed the load address itself, which it
can do if something else is occupying that memory location.  In that case I
guess it's impossible to determine, is that correct?

A few years back we wrote an utility to find the line number (based on
Christophe Gevrey's source code) as well as func/proc calling hierarchy, it
served us well over the years.

 

I tried our utility on your map file and it can't find the address, I
suspect the linker Image Base you provided is incorrect.

Cheng

I have written a DLL for my Delphi 7 application.  It's a C compatible DLL
with no Delphi memory sharing etc.

 

It works fine for me and several other users, but one user is regularly
receiving an access violation in this DLL at a specific address.  I have a
detailed .MAP file and I'm hoping someone can help me find the source code
line number from this.

 

I've not done this before and I'm hoping someone can help.

 

The access violation is at 04148AD1.

 

Here is the map file.

I believe the linker image base was set to $01500000 at the time of this
compile.

 

I hope this is possible.

 

Thanks,

Ross.
