I have tested the compiled fmt command for giving out a formatted output of a

[request-sponsor] Fix ready for Bug ID 6355611

Hello

I have the fix ready for the following bug:

Bug ID: 6355611
Synopsis: setbuf misuse
Description: A subtle bug exists in fmt.c (using the source cross referencer 
the bug is visible else where). main() calls setbug passing a buffer that 
exists in main's stack. It can occur that the data in the buffer is not used 
until exit causes the buffer to be flushed, however the buffer is technically 
out-of-scope and should not be used.
Category: utility   Sub-Category: formatter

I would request someone to sponsor this bug.

I have have already submitted my Sun Contributor Agreement, but I am still 
awaiting my SCA number.

Regards
Souvik Das Gupta
