Bug #: 13929
Summary: Watchpoint missed on next
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: breakpoints
AssignedTo: unassigned@sourceware.org
ReportedBy: eager@eagercon.com
Classification: Unclassified
Test case gdb.base/gdb11531 fails on x86_64, Linux-2.6.32 (CentOS 6.0).
When "next"ing over an assignment which should trip a watchpoint, the
watchpoint is not seen.
Test case:
struct rec
{
int x;
double y;
int z;
};
static struct rec myrec;
int
main ()
{
myrec.x = 5;
myrec.y = 3.4;
myrec.z = 56;
myrec.x = 78;
return myrec.x;
}
(gdb) break main
(gdb) run
-- stops at myrec.x = 5;
(gdb) watch myrec.x
(gdb) next
-- assignment of myrec.x not reported

I think this is PR7143. Try deleting the "main" breakpoint before "next"ing.

The watchpoint not triggering at the same location as a breakpoint is exactly
the problem.
