[my 'errno' script]

ERRNO_HEADERS="/usr/include/asm-generic/errno-base.h /usr/include/asm-generic/errno.h"
if [ "$1" = "" ]; then
grep -E "[[:space:]]$ERR[[:space:]]/" $ERRNO_HEADERS

With that information, you can check where the function may through 
EINVAL. It's not a common error, though (we may need to document reasons 
for it). Do you get further messages? Try to attach a debugger to find 
out with call in rt_pipe_create (lib/alchemy/pipe.c) returns this code.
