[Samba] conflict in lib/snprintf using gcc-2.95.3 on HPUX 11. 00

[MCCALL,DON (HP-USA,ex1)]

Hi Rene,
that's correct.
The patch that Yasuma shows prevents the core by giving a buffer for
vsnprintf to 
use, instead of "0" (as I recall the core is produced when the system tries
to resolve
the buffer address of '0') - but bottom line is, even with this the snprintf
check for 
C99 compliance should fail, and Samba should be using it's internal version
instead.
Hope this helps,
Don

Hi Yasuma,

You're correct: this bug caused a core-dump and should be cleaned-up. But
still HP/UX 11.00 seems to have no C99-compliant snprintf. Can you confim
this Don?
