Hello,

I'm just downloading the trunk version now and building it. I'd be surprised if it was an issue, but it's probably worth mentioning I'm using the ROOT Builder program instead of Cygwin, as that's not setup on my machine.

As I said, the result with -c and without -p is it crashes, and without either:

Limitation: Reference member not supported. Please use pointer D:/root/include\T
GenericClassInfo.h(36)

To summarise, with version 5.24/00 (downloaded as a binary from http://root.cern.ch/drupal/content/production-version-524, using the "Release" version for VC++ 9):

As soon as I finish the build, I'll let you know the results for the trunk version.

Regards,

Mike

Hi,

this got fixed in the trunk. Can you try without -p?

Cheers, Axel.
