[Bug fortran/26201] [4.1/4.2 regression] __convert_i4_i8 written to a module.
--- Comment #3 from eedelman at gcc dot gnu dot org 2006-02-15 21:20 --- I can't reproduce the problem with MUMPS on Linux/x86 (mainline revision 11, 4.1 revision 110989). Assuming that Steve used a 64 bit processor, it seems that for this code the bug is visible only on 64 bit systems. (The fact that problem occurs for the function __convert_i4_i8 also indicates that, since conversions from 4 byte to 8 byte integers happens more often on 64 bit systems than on 32 bit ones.) The VASP code I do not have available, so I can't test that one. (Since it is about reals rather than integers, it's not unlikely that that would be reproducable on 32 bit systems.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26201

Here's something that exhibits this behaviour... If I may say so, I find it *really* weird: removing things which do not seem to be related to that seem to make it disappear though...
