I have a mindmp file from a target’s application crash. Is it possible for me to rebuild the dll/pdb files for a version of software and have windbg load symbols correctly?
My problem is that our pdb files are only kept for major releases (unfortunately). This is a daily build, which I can rebuild myself, but I’m getting tripped up on errors.
With !sym noisy on: ‘image header does not match memory image header.’
DBGENG: C:\...\XXX.dll image header does not match memory image header. DBGENG: XXX.dll - Partial symbol image load missing image info DBGHELP: Module is not fully loaded into memory. DBGHELP: Searching for symbols using debugger-provided data. DBGHELP: C:\...\XXX.pdb - mismatched pdb Note I’ve build the pdb with the dll, they are from the same RELEASE directory (should I be building debug?)
Theses are release builds (as release builds are installed on the target and crashing) should I be somehow using the debug build dlls to get more symbol information?
In my experience probably not.
If you have the exact build directory and build with the exact same compiler settings then this might work. You definitely will not be able to load symbols from a debug build against a release crash dump.
You will need to turn on the ‘load anything’ options: .symopt+0x40 to get windbg to ignore the timestamp differences.
