            Bug ID: 105544
           Summary: gdc fails to compile d source from stdin
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: fabian@ritter-vogt.de
  Target Milestone: ---

Reading code from stdin doesn't work. strace shows that it attempts to read
from a file "<stdin>" repeatedly.

~> echo "pragma(msg, int(__VERSION__));" | /usr/bin/gdc -x d -
<stdin>:2:1: error: Outside Unicode code space
<stdin>:2:1: error: Outside Unicode code space
<stdin>:2:1: error: Outside Unicode code space
<stdin>:2:1: error: Outside Unicode code space
...
<stdin>:2: error: no identifier for declarator =EF=BF=BD=EF=BF=BD=EF=BF=BD=
=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD...

Expected behaviour:

~> echo "pragma(msg, int(__VERSION__));" > ver.d; /usr/bin/gdc-11 -x d
/tmp/ver.d
