--- Comment #1 from Vladimir Panteleev  ---
The problem seems to be that the same object file name is used when reading
from stdin:

$ echo 'void main() {}' | dmd -v -run - | grep ^cc
cc __stdin.o -o /tmp/dmd_runIAGsLe -m64 -Xlinker --export-dynamic
-L/home/vladimir/opt/dmd/bin/../lib64 -Xlinker -Bstatic -lphobos2 -Xlinker
-Bdynamic -lpthread -lm -lrt -ldl

This cannot work reliably in multiple threads, as several concurrent DMD
instances will write __stdin.o, and several concurrent linkers will attempt to
read it.
