Apology accepted. FWIW, looking at your strace output and streamio_4.f90, it seems this fd 0x3 isn't a special file and the ftruncate calls succeed, so my patch shouldn't have had any effect. But you know that now. I did a similar strace for streamio_4 on x86_64-unknown-linux-gnu with r132965 and came to the same conclusions; the lots-of-small-increment ftruncate-calls were introduced with r132512 and not affected by my patch. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35632
