## test1.c ##

typedef union {
        unsigned all :8;
} x_t;

char test_x (char sv)
{
        x_t error;

Fix:

no known fix yet.
Comment 2 Dara Hazeghi 2003-08-25 14:08:50 UTC 
Confirmed. Occurs only with optimization though (not at -O0) so changing category accordingly.
Comment 3 Bernardo Innocenti 2003-09-27 03:33:47 UTC 
Does not happen any more on mainline (20030927).
Comment 4 Andrew Pinski 2003-12-28 03:30:04 UTC 
Fixed for 3.4.
