Emmanuel, we can do *nothing* without a compilable source code showing the bug.
Better if the testcase can compile and link into a standalone executable which
segfaults. But if this is impossible, at least give us a compilable file
containing the buggy_feature function and all the declarations needed to
compile it. From there, we can start analyzing the dumps and check if there is
something wrong going on.
Another way you can help is pinpointing the exact optimization option which
triggers the bug. The manual contains a list of all options implied by -O1, so
you can start from there and remove them one by one (-O1 -fno-this -fno-that)
until you find which one triggers the bug.
