https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102802 TC changed: What|Removed |Added CC||rs2740 at gmail dot com --- Comment #3 from TC --- No, this is valid. B's operator() is not visible, but its conversion to function pointer is, and that introduces a surrogate call function during the overload resolution for the function call expression (and it's selected because it is the only viable candidate).

GCC misses the -Wunused-but-set-variable in the some code (GCC and Clang output
can be seen in https://godbolt.org/z/7658M4qra).
I first found a bug caused by the following code, in which no compilers warn:
void ioapic_set_max_vectors(void *ioapic_base, int mre_count)
{
u32 reg;
u8 count;
reg = io_apic_read(ioapic_base, 0x01);
count = reg >> 16;
if (mre_count > 0)
count = mre_count - 1;
// reg is defined but not used after this
reg &= ~(0xff << 16);
reg |= count << 16;
// ``count`` should be ``reg`` in the following line
io_apic_write(ioapic_base, 0x01, count);
}
I think that's because the variable ``reg`` is only unused in part of the
control flow, so I change the code as following. However, GCC doesn't warn on
this either.
void ioapic_set_max_vectors(void *ioapic_base, int mre_count)
{
u32 reg;
u32 new_reg;
u8 count;
reg = io_apic_read(ioapic_base, 0x01);
count = reg >> 16;
if (mre_count > 0)
count = mre_count - 1;
// new_reg is defined but not used
new_reg = reg & (~(0xff << 16));
new_reg |= count << 16;
// ``count`` should be ``new_reg`` in the following
io_apic_write(ioapic_base, 0x01, count);
}
[Bug fortran/102891] Passing real part of complex type component using w%z%re to a subroutine gives erroneous value of dummy argument
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102891 --- Comment #2 from anlauf at gcc dot gnu.org --- Adding to main the lines print *, size (transfer ( w%z%re ,[1.0_dp])) print *, size (transfer ([w%z%re],[1.0_dp])) prints 4 2 whereas e.g. print *, size (transfer ( real (w%z, kind (w%z%re)) ,[1.0_dp])) print *, size (transfer ([real (w%z, kind (w%z%re))],[1.0_dp])) prints 2 2 The issue is likely with the combination of array/array constructor and the inquiry %re .

Hmmm, maybe not. It doesn't look like a threading thing after a quick glance. We only thread 1 path, in both 11.2 and trunk: a.c.193t.dom3: [4] Registering jump thread: (11, 3) incoming edge; (3, 5) joiner (5, 12) normal; And it's actually in DOM which has been largely untouched in this release. Could someone bisect this?
