Re: miata and samba3

Hi every one,

sorry for the delay, had other priorities, but when i attach gdb to smbd
I get the following:

<interruption !!!!!>
Seems to me a glibc problem, recompiled glibc with CFLAGS="-mcpu=ev4
-pipe" (previous "-mcpu=ev56 -O3 -pipe") no more problems!!!!!
fast conclusion, no -O3 but -O2 in your make.conf and recompile glibc
(glibc-2.3.2-r12)

was trying to move/copy a file on a windowsXP system from local drive to
the network drive.

Hopefully It gives some more inside into the problem.

With regards,
