Access JCL Debug information contained in executable?

Question

Is there a way to access the Jedi Debug Information (JDBG) contained in an executable?

Microsoft debugging tools have pointed me to a stack chain in

Create a TJclDebugInfoBinary object, using the HModule handle you get from LoadLibrary. Then call GetLocationInfo on it. That's all TJclDebugInfoList would have done anyway, except it has some helper methods to map addresses from the current address space to the modules they correspond to, whereas when you do it manually, you'll have to already know which module the addresses belong to. (But the crash dump already told you that part, so you don't need the help of the list class.)

You'll probably have to massage the addresses because the base address of the module at the time of the crash is not going to be the same as when you've loaded it with LoadLibrary.

The JCL debug information is not stored in a resource. It's stored in a PE section named JCLDEBUG. See the uses of PeMapImgFindSection32 and PeMapImgFindSectionFromModule in JclDebug.pas.
