I'm using FAT as filesystem. We have same phenomenon for FAT12 or FAT16!

	Hello,

	 

	maybe I found a bug in getcwd().

	 

	We're using RTEMS 4.0 with Gaisler-Aeroflex....

	With our libraries I get an erroneous string when directory-depth is about 4 folders from root!

	When I use this string to read directory it crahes!

	 

	 

	Is there a limitation of string-length?

	I get the same results for

	 

	               Char buffer[200];

	getcwd(buffer,sizeof(buffer));

	 

	or

	 

	               char* ret = getcwd(NULL,0);

	 

	 

Is this with the IMFS? What BSP?

Can you put together a full test example so we can
see what is really happening? 

There is a POSIX constant for PATH_MAX as I recall but
it is quite large.
