--- Comment #10 from Thibaut M. <dumoulin.thibaut at gmail dot com> ---
I understand the patch
https://gcc.gnu.org/legacy-ml/gcc-patches/2016-12/msg01158.html has not been
applied.
The dynamic constructor of global variable `pool emergency_pool;` in
`libstdc++-v3/libsupc++/eh_alloc.cc` remains and is still allocating
unconditionally at least 2.5ko on the heap.

I was not able to find the thread about "exception handling" of 2020-05, could
you point it out or detail the conclusion please?
Has a solution been found for embedded systems with very limited resources? In
this case for example, C++ exceptions can be disabled and this emergency pool
not needed.
