------- Comment #3 from pinskia at gcc dot gnu dot org 2007-02-19 06:53 -------
Confirmed, reduced testcase as far as I can do it:
typedef struct rxvt_term *rxvt_t;
struct rxvt_salloc {
struct chain {
struct chain *next;
};
chain *firstline;
unsigned int firstfree;
inline void alloc ();
};
struct rxvt_perl_interp {
bool invoke (rxvt_term *term);
};
extern struct rxvt_perl_interp rxvt_perl;
struct rxvt_term {
int term_start;
int *row_buf;
rxvt_salloc *talloc;
void scr_reset (int pend, int qlines);
};
inline void rxvt_salloc::alloc ()
{
if (firstline)
firstline = firstline->next;
else {
if (firstfree > 65536)
firstfree = sizeof (chain);
firstfree += firstfree;
}
}
void rxvt_term::scr_reset (int pend, int qlines) {
do {
int *qline;
for (int qrow = term_start; qlines--; qrow++)
{
qline = row_buf + qrow;
talloc->alloc ();
talloc->alloc ();
}
qline[0] &= ~0x0001;
talloc->alloc ();
talloc->alloc ();
} while (term_start != pend);
rxvt_perl.invoke (this);
}
