This testcase failed to compile with gcc 4.3.4 143496: /usr/gcc-4.3/bin/gcc -S -march=native -funroll-loops -fno-rename-registers -ffree-line-length-512 -g -ffree-form -ftime-report -c -O3 testcase.f90 -fmem-report f951: out of memory allocating 6998974688 bytes after a total of 674205696 bytes on Linux/Intel64 with 4GB RAM and 2GB swap. Gcc 4.4.0 revision 143680 compiles it on the same machine. -- hjl dot tools at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |FIXED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38583
