Patch which might help:

The other thing which might help here is trying to find more functions which
can have nothrow on them which should help compile time. I had a patch which
did this at the tree level but never finished it.

And we can hope that the SSA inliner will do better on the temporaries, but I
guess the resulting CFG will be unchanged. Penaltizing try/finally in
estimate_num_insn_1 instead of declaring them "/* Containers have n

At .ssa we have for the posted fragment the following loads of basic blocks
and exception objects:
:
D.68636_176 = &this_1->iso639_1;
D.68641_177 = operator[] (D.68636_176, &D.68639);
:

Basically, the initialization sequence expands to a sequence of (.03.gimple):
__comp_ctor (&D.68628);
try
{
__comp_ctor (&D.68629, &"ab"[0], &D.68628);
