InternetOpenUrlA crashes

[jj2007]

Does anybody have experience with debugging InternetOpenUrlA? Both Olly and DebugHeap complain bitterly about exceptions. With Olly, I end up with an invalid jump to 00000001h; with DebugHeap, I can recover by clicking "no". There is clearly something going on inside that call, but no answers on the web - just one question on SOF: InternetOpenUrl exception thrown (Kernelbase.dll) - Unknown interface but no answer

Hi Jochen,

Could you try x64dbg? It didn't throw an exception in my test :

Hi Erol,

Thanks for the suggestion. I just downloaded the latest version, and X32 shows the same behaviour. Besides, I can't convince x32Dbg to show me symbols (no problem with Olly)

It could be a Windows 7-64 bug. The exception doesn't show in my XP VM.

P.S.: No more crash if I ignore exception 800706B5 alias "unknown interface"

It's mysterious: There is RPC_S_UNKNOWN_IF, but its value is decimal 1717. The 800706B5 does not appear in the VC header files, and yet a search for it has many hits to known problems, mainly related to Windows updating, i.e. access to Internet.
