Hi, this program is btw invalid, you know? You aren't allowed to access in fun1 the same I/O unit (unit=* is OUTPUT_UNIT).
"An input/output statement that is executed while another input/output statement is being executed is a recursive input/output statement. A recursive input/output statement shall not identify an external unit that is identified by another input/output statement being executed except that a child data transfer statement may identify its parent data transfer statement external unit." (F2008,9.12 Restrictions on input/output statements) Regards, Kai 2012/1/6 xunxun <[email protected]>: > Hi, all > > My friend found a MinGW/MinGW64 Gfortran program io dead lock issue.
