Minimum :

Information regarding the platform, the compiler , libc version used, 
gdb version used would be useful for anyone to make a start .If possible 
a complete script of the session where you had such a problem would 
definitely be a good starting point (man script)


Bonus :
A small testcase showing a similar scenario would help.
