[Bug fortran/54725] cross gfortran always searches host paths (e.g. /usr/include)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54725 Kacper Kowalik xarthisius.kk at gmail dot com changed: What|Removed |Added CC||xarthisius.kk at gmail dot ||com --- Comment #2 from Kacper Kowalik xarthisius.kk at gmail dot com 2012-09-27 06:00:32 UTC --- (In reply to comment #1) You forgot to explain what you think is not quite right. gfortran searches only directories where it may have installed some modules and directories that you explicitly add via -I. Because when you do cross compilation you don't want your compiler to pick up host modules. Apart from that ^^ shouldn't frontends behave in a consistent manner?

If one does not use an endless loop but a finite loop, it shows no leakage with neither valgrind nor totalview. Also the result seems to be fine - except that the memory consumption simply grows ...
