Make sence on valgrind... hey does the gcc on an operton default to a 64bit linking or do you have to do something like -64 for all the objects? I am thinking about sun and gcc for example where you cannot compile 64 bit without explicity telling the linker to link the 64 bit libs. Just a thought I know sun solaris is totaly diffrent than linux on operton. If it is accessing a 64bit NULL value, but only after completing the output from md5. very odd... I will check this on a sun after compiling 64bit. will let you know in a sec. on sun 32bit it works just find. -leif > [EMAIL PROTECTED]:~/gdb-6.0> ./gdb/gdb > GNU gdb 6.0 > Copyright 2003 Free Software Foundation, Inc. > GDB is free software, covered by the GNU General Public License, and you > are > welcome to change it and/or distribute copies of it under certain > conditions. > Type "show copying" to see the conditions. > There is absolutely no warranty for GDB.
