Problem with unsigned char * data

[Emilio Ugo GIUFFRIDA]

Gentlemen,

I have a problem with gdb/Insight :-(

On a board, when a "unsigned char *" pointer is badly initialized to 
0xffffffff( that for us is outside the memory ), trying to print the pointer's value in the local variable window or in the watchpoint window makes the GUI crash.

Using the gdb console, the answer is quite verbose, but correct:
(gdb) print pt1
$6 = 
Error: Error in st200emu :  Cannot read buffer at memory adress 0xffffffff
Adaptor error on: read memory access at address  (Exception 5 while executing ROM command)

It seems that gdb tries to read at 0xffffffff and, for pointers to unsigned char, displays by default the string pointed. 

Do you know if there is a gdb option disabling this behaviour?


Best regards,

Emilio
