[PATCH] fix for PR 59825

[Iyer, Balaji V]

Hello Everyone,
        Attached, please find a patch that will fix PR 59825. The main issue 
was array notations occurring in COMPOUND_EXPR. This patch should fix that and 
fix the rank_mismatch2.c test-case ICE.
        
        Ok for trunk?

Thanks,

Balaji V. Iyer.
