I was porting a code that uses chdir, but it seams that doint chdir("./") crashes somehow the psp, the line number is in the path_absolute stuff of newlib
I don't have always the usb cable, but It's reproducible, I'm not sure that the string passed is "./", it maybe also a non null terminated string, in this case is a programming error and not a bug in the lib (the code is not mine).
I'll post soon my results
