Some applications like "maple v5", "tecplot" can not run under Redhat 7.0
(they run well under 6.2).  For instance,

   $ ./maple
    bash: ./maple: No such file or directory

run with strace:

   $ strace -f  ./maple
   execve("./maple", ["./maple"], [/* 27 vars */]) = 0
   strace: exec: No such file or directory

But the file exists!

    Using "objdump" I found that those files (tecplot and maple) which can
not run have the headers like that:

	./maple:     file format elf32-i386
 
	Disassembly of section .interp:
 
	080480d4 <.interp>:
 	80480d4:       2f                      das	
 	80480d5:       6c                      insb   (%dx),%es:(%edi)
	80480d6:       69 62 2f 6c 64 2d 6c    imul   $0x6c2d646c,0x2f(%edx),%esp
 	80480dd:       69 6e 75 78 2e 73 6f    imul   $0x6f732e78,0x75(%esi),%ebp
	80480e4:       2e 31 00                xor   
%eax,%cs:(%eax)                    

The .interp section start at 080480d4., while the runing applications has
header,

	/bin/ls:     file format elf32-i386
 
	Disassembly of section .interp:
 
	080480f4 <.interp>:
	 80480f4:       2f                      das
	 80480f5:       6c                      insb   (%dx),%es:(%edi)
	 80480f6:       69 62 2f 6c 64 2d 6c    imul   $0x6c2d646c,0x2f(%edx),%esp
	 80480fd:       69 6e 75 78 2e 73 6f    imul  
$0x6f732e78,0x75(%esi),%ebp   

which starts at 080480f4 or other place.

	It seems a bug in kernel or glibc prevent those applications be
recognized.
