Hello everybody -
This is a followup on my old bug report. Now it is about the recent
snapshot...
I. Hardware/software configuration:
1. The machine: Alpha 21264 (ev6) dual-CPU
RedHat Linux 5.2, kernel 2.2.1 (SMP)
2. The compiler:
Reading specs from /bb/abel2/egcs/lib/gcc-lib/alphaev6-unknown-linux-gnu/egcs-2.93.11/specs
gcc version egcs-2.93.11 19990307 (gcc2 ss-980929 experimental)
II. Internal error #1
1. The file:
===============================================
#define MAX_BLOCKS 12
#define true 1
typedef unsigned char boolean;
typedef struct bar_t {
struct {
boolean over_allocated;
} *block[MAX_BLOCKS];
} bar_t;
struct foo_t {
bar_t **bar;
struct
{
double p, i;
boolean oa;
} ba[MAX_BLOCKS];
} ;
void
end_tranches(struct foo_t *foo)
{
long t, num_p, i;
long forlim;
for (i = 1; i <= forlim; i++) {
if (foo->ba[i-1].p - 1.0e0 > 1.0e-8) {
if (foo->ba[i-1].oa) {
}
else {
error_message(132, 0, 9, true, true, 0, 3);
}
}
if (foo->ba[i-1].i - 1.0e0 > 1.0e-8) {
if (foo->ba[i-1].oa) {
(*foo->bar)->block[i-1]->over_allocated = 1;
}
else {
error_message(132, 0, 9, true, true, 0, 3);
}
}
}
}
===============================================
2. The error:
===============================================
$ gcc -O2 -g egcs_crash3.c
egcs_crash3.c: In function `end_tranches':
egcs_crash3.c:49: internal error--insn does not satisfy its constraints:

(reg:QI 3 $3)) 288 {movsi-1} (nil)
(nil))

===============================================
III. Internal error #2
1. The pristine file (preprocessed version follows):
===============================================
#include <string.h>
typedef struct foo_t {
double foo, bar;
} foo_t;
void
foobar(void)
{
long maddr;
foo_t payment;
memcpy(maddr, (long)(&payment), sizeof(foo_t));
}
===============================================
2. The error:
===============================================
$ gcc -O2 -g egcs_crash1.c
egcs_crash1.c: In function `foobar':
egcs_crash1.c:15: warning: passing arg 1 of `memcpy' makes pointer from integer without a cast
egcs_crash1.c:15: warning: passing arg 2 of `memcpy' makes pointer from integer without a cast

Please submit a full bug report to `egcs-bugs@egcs.cygnus.com'.
See <URL: http://egcs.cygnus.com/faq.html#bugreport > for details.
$ gcc -g -c egcs_crash1.c
