You don't say what operating system or shell this is using. I'm going to guess some distro of Linux and the Bash shell...

Check the filenames that your wildcard expands to. It's likely there's a character in there that when expanded in the gdb command line is giving the shell some grief.
Some rules for typing in shell commands:
1. Always put double quotes around your dollar-sign variables. (It's only wrong about 3 times in 1,000 so you've got a 99.7% chance of being right.
)
2. Use
$(...) instead of
`...`. (Won't matter in this particular case, but it's a good idea for a variety of reasons.)
3. Don't use a bunch of pipes when they're not necessary. (In this case using gdb is
way overkill as the file command will likely give you the right data. Using a command like
set -- $(file "$i") eliminates all of the pipes and only requires a single fork/exec because the set command is builtin to the shell.)
Otherwise I agree with TonyFullerMalv; you need to go back to basics and test out each piece of your command line. In particular, you need to know what data is going into the loop (such as the filenames).

TAU_MAPPING_LINK(3) TAU Mapping API TAU_MAPPING_LINK(3)
NAME
TAU_MAPPING_LINK - Creates a mapping link
SYNOPSIS
C/C++:
TAU_MAPPING_LINK(FunctionInfo FuncIdVar, unsigned long Key);
DESCRIPTION
TAU_MAPPING_LINKcreates a link between the object defined in TAU_MAPPING_OBJECT (that identifies a statement) and the actual higher-level
statement that is mapped with TAU_MAPPING. The Key argument represents a profile group to which the statement belongs, as specified in the
TAU_MAPPING macro argument. For the example of array statements, this link should be created in the constructor of the class that
represents the expression. TAU_MAPPING_LINK should be executed before any measurement takes place. It assigns the identifier of the
statement to the object to which FuncIdVar refers. For example
EXAMPLE
C/C++ :
class MyClass {
public:
MyClass() { }
~MyClass() { }
void Run(void) {
TAU_MAPPING_OBJECT(runtimer)
TAU_MAPPING_LINK(runtimer, (unsigned long) this);
TAU_MAPPING_PROFILE(runtimer); // For one object
TAU_PROFILE("MyClass::Run()", " void (void)", TAU_USER1);
/* ... */
}
};
int main(int argc, char **argv) {
TAU_PROFILE_INIT(argc, argv);
TAU_PROFILE("main()", "int (int, char **)", TAU_DEFAULT);
MyClass x, y, z;
MyClass a;
TAU_MAPPING_CREATE("MyClass::Run() for object a", " " ,
(TauGroup_t) &a, "TAU_USER", 0);
TAU_MAPPING_CREATE("MyClass::Run() for object x", " " ,
(TauGroup_t) &x, "TAU_USER", 0);
TAU_PROFILE_SET_NODE(0);
cout <<"Inside main"<<endl;
a.Run();
x.Run();
y.Run();
