Hi Chris.
You can clone this repository:
https://github.com/ttsiodras/EmbeddedCoverage
...and then use different build invocations to easily reproduce - like
this:
First, with an older toolchain:
=================================
(master)$ /opt/rtems-4.11/bin/sparc-rtems4.11-gcc -v
Using built-in specs.

With the old toolchain, CTOR_LIST contains this:

Do you have a test case with the compile and link commands that can be
used to
show the problem?
