Error reloading library in 5.15.04

[dva]

Hello ROOTers.
After the v5.15.04 installation i found a new feature, when trying to reload an ACLICed
library. Have a look at the following example:

[rootmacros] > root

Hi,

We can reproduce the problem. We are looking for the best solution. In the meantime, create a canvas (or explicitly load libGpad) before loading your pre-compiled library.

Cheers,
Philippe.

This problem is now fixed in the CVS repository.

Cheers,
Philippe
