I have installed and made RCG2.9.6 the default build environment. I have compiled all th H1 models (102 of them) using 2.9.6, there are no errors in the build. The IPC file was created from new, it is 6 channels smaller than the old file.

This was a make only, it was not installed. I have reverted the original IPC file in case models are restarted this weekend. I'll complete the make/make-install process next Tuesday prior to H1 upgrade to 2.9.6.
