Hi All, This patch is very straightforward. The PR itself was fixed by not freeing the parameterized components on leaving function scope. The lhs expression in the assignment had pointers to parameterized components that were overwritten on assignment, thereby causing some memory leakage. This is fixed in trans-expr.c by deallocating them before assignment. Bootstrapped and regtested on FC23/x86_64 - OK for trunk? I will commit in 24 hours if I receive no contrary comments.
