I could notice in the build log on sid the following warnings:
hwengine.pas(626)
Warning: "crtbeginS.o" not found, this will probably cause a linking failure
hwen
gine.pas(626) Warning: "crtendS.o" not found, this will probably cause a linking
failure
On the other hand these files seem to belong to libgcc-5-dev on my system
$dpkg -S /usr/lib/gcc/x86_64-linux-gnu/5/crtbeginS.o
libgcc-5-dev:amd64:
/usr/lib/gcc/x86_64-linux-gnu/5/crtbeginS.o
Can you please check if they are availables on the arm box you are using?
The reason I think these warnings are related is that stdin/stdout are open by
parent process so may be related to the C code initialization.
I can probably be completely wrong, but let's check this first.
