TMultipartFormData issue with 12.3, but not 11.3

[alank2 5]

This is C++ Builder, but it is using System.Net.Mime.pas which contains TMultipartFormData.

 

Building with 11.3 works fine no errors, but building with 12.3 will cause a crash when I try to delete a pointer to TMultipartFormData.

 

I added System.Net.Mime.pas and stepped into it and it calls:

 

 

If I step over "FStream.Free" it crashes.  If I step into it:

 

 

If I step over Destroy it crashes.  If I step into it, it goes into assembly:

 

 

I can see a lot of differences between the the 22.0 and 23.0 versions of System.Net.Mime.pas.

 

Any ideas on how to I can resolve this with 12.3?

Look at the crash details to get hints as to what is going on. Note you didn't post any and "crash" is very little to go on.

 

Guessing it is the CALL that crashes due to the object reference being no longer valid. Perhaps owned objects are getting freed automatically or earlier than before. Not sure which code is yours (if any) so hard to tell.
