As next step, can you remove it ?
Some can interfere also when disabled.

In addition you can run

  strace -o pipe.strace cat test.txt |head

on fix and removable drive. May be will give some additional hint.

To see if any program is injecting dll's on your system
you can also looks on /proc/self/maps

On my W7 cygwin 32bit

$ cat /proc/self/maps | awk '{print $6}' |sort -u

/cygdrive/c/Windows/System32/apisetschema.dll
/cygdrive/c/Windows/System32/locale.nls
/cygdrive/c/Windows/System32/ntdll.dll
/cygdrive/c/Windows/System32/wow64.dll
/cygdrive/c/Windows/System32/wow64cpu.dll
/cygdrive/c/Windows/System32/wow64win.dll
/cygdrive/c/Windows/SysWOW64/kernel32.dll
/cygdrive/c/Windows/SysWOW64/KernelBase.dll
/cygdrive/c/Windows/SysWOW64/ntdll.dll
/cygdrive/c/Windows/SysWOW64/sysfer.dll
/usr/bin/cat.exe
/usr/bin/cygiconv-2.dll
/usr/bin/cygintl-8.dll
/usr/bin/cygwin1.dll

so only cygwin or MS shared lib.

I forgot one question :
 did your XP system ever worked with a cygwin installation ?

I doubt latest cygwin changes broke XP, but may be it happens.

Marco
