Regression in wininet between 0.9.23 and 0.9.24

[Pavel Troller]

Hi!
  I would like to report a regression in wininet.dll, causing Dreamcom Kubik
SMS to crash as follows:

wine: Unhandled page fault on read access to 0x00000000 at address 0x7e687b86 (thread 0013), starting debugger...
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x7e687b86).

I was doing "cvs bisect" in dlls/wininet and found that the problem lies
between .23 and .24 - from .24 on it crashes, .23 is still OK. So now
I'm using HEAD wine with .23 wininet and the program is happy.

                   With regards, Pavel Troller

Thanks, but the right place to report bugs is http://bugs.winehq.org

It's much easier to use Git for regression testing.  It will give you an 
exact commit ID which you can put in your bugzilla report.
