It figures.  IIRC Bash uses the termios functions to read console input.  
The DJGPP implementation of termios (written AFIK by Daisuke Aoyama and 
used almost exclusively by Bash) hooks calls to the `read' function and
makes the library call `__libc_termios_read' instead.  See the library 
sources on src/libc/posix/unistd/read.c and 
src/libc/posix/termios/tminit.c, for the gory details.  It seems that the 
problem is somewhere inside `__libc_termios_read' or its subroutines.

So I suggest to get the sources of the above two modules from 
djlsr201.zip, compile them with -g, link Bash with them, and step inside 
`read' and `__libc_termios_hook' with GDB.  I hope you will be at least 
able to see what part there hangs on you, and we could then scratch our 
heads to try to figure out why.
