I had MCU instead of CPU variable used.

[Bug ld/23803] New: __init_array_end - __init_array_start < 0
https://sourceware.org/bugzilla/show_bug.cgi?id=23803
Bug ID: 23803
Summary: __init_array_end - __init_array_start < 0
Product: binutils
Version: 2.30
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: schorsch_76 at gmx dot de
Target Milestone: ---
The C++ Objects get instantiated from __libc_init_array. On this MCU it is
newlib. It initialize the c++ objects like this
https://github.com/redox-os/newlib/blob/master/newlib/libc/misc/init.c
/* Iterate over all the init routines. */
void
__libc_init_array (void)
{
size_t count;
size_t i;
count = __preinit_array_end - __preinit_array_start;
for (i = 0; i < count; i++)
__preinit_array_start[i] ();
_init ();
count = __init_array_end - __init_array_start;
for (i = 0; i < count; i++)
__init_array_start[i] ();
}
on my MCU (in the reset handler) i use gdb to print these variables, but they
are like this:
#0 0x0800017c in Reset_Handler ()
(gdb) print __init_array_start
$1 = 134218568
(gdb) p __init_array_end
$2 = 134217996
(gdb) p __init_array_end - __init_array_start
$3 = -572
As count is an size_t it is unsigned and the loop doesn't stop. But end should
be greater than start in any case.
I created a very minimalistic c++ Project on Stm32F103RBT6 with the toolchain
from arm. It uses binutils and also tried different other compilers. like from
debian but all show this behaviour.
