Bug #: 56555
Summary: read from pipe
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: fu...@hawaii.edu
When reading from stdin in a simple pipe, the Fortran runtime reports an "End
of file" error. See the self contained example below. It was done on a
Debian-testing system. The shell is a symlink to /bin/dash .
Regards,
Ryo
