Any reason why windbg won’t load symbols for my module. I issue following command…
.reload /f /i Mymodule.exe=0x1234567887654321
Ofcourse 0x1234567887654321 is loaded base address of the module. And I do have .pdbs in the right folder…
My guess is pdbs could be generated with optimization ON, but I could be wrong here…
What’s the error message? What does output from ‘!sym noisy’ says? Any
chance you’re mixing x86 with x64 binaries (pdb<->exe)?
Also if this is minidump then you’ll need to setup ‘image file path’
(see ‘.exepath’).

I verified its x64 binary and pdb’s are also for x64 binary…
I have .dbg and/or .pdb both in same directory still no help…
Here’s what symnoisy displays…
DBGHELP: No debug info for Mymodule.exe. Searching for dbg file
SYMSRV: d:\localsymbols\Mymodule.dbg\52837BFA91840\Mymodule.dbg not found
SYMSRV: http://msdl.microsoft.com/download/symbols/Mymodule.dbg/52837BFA91840/Mymodule.dbg not found
DBGHELP: Mymodule.exe missing debug info. Searching for pdb anyway
DBGHELP: Can’t use symbol server for Mymodule.pdb - no header information available
DBGHELP: Mymodule- public symbols
c:\sym\Mymodule.dbg - unmatched
c:\sym\Mymodule.pdb - unmatched
if you want to load unmatched pdb you can issue
.symopt +0x40
this flag 0x00000040 - SYMOPT_LOAD_ANYTHING
will allow you to load any outdated / mismatched pdbs to load at a
given base and size
