Note -O2 -finline-functions is enough to reproduce the bug.

: Search converges between 2004-10-26-161001-trunk (#611) and 2004-11-03-014001-trunk
(#612).
Really only -O1 -finline-functions is needed.

I forgot to say that the reduced testcase only fails at -O1 now (I don't know why).
Also here is the C example (which is just slight changes to C++ example):
#define bool _Bool
typedef struct QChar {
unsigned short ucs;
} QChar;
int tibetan_form( const QChar *c );
static inline int tibetan_nextSyllableBoundary( int start, bool *invalid, QChar *uc)
{
int pos = 0;
int state = tibetan_form( &uc[pos] );
if ( state != 1 )
{
if ( state != 0 )
*invalid = 1;
goto finish;
}
finish:
*invalid = 0;
return start+pos;
}
void tibetan_shape( int from, int len, QChar *uc)
{
int sstart = from;
int end = sstart + len;
while ( sstart < end ) {
bool invalid;
tibetan_nextSyllableBoundary(sstart, &invalid, uc );
}
}

int baz (int *);
void

The binary search converges between 2004-10-27 17:40GMT and 2004-10-27 17:50GMT,
so this patch is likely to have caused the segfault.

Assigning to Danny as the problem is that we are trying to clean up the CFG before fixing up the
