Dear Maintainer,
I could reproduce this issue with version 2.26.20160125+Atmel3.6.2-1.
Program terminated with signal SIGILL, Illegal instruction.
#0 0x0000aaaae70f20e8 in e843419@0011_00000103_e2c ()
(gdb) bt
#0 0x0000aaaae70f20e8 in e843419@0011_00000103_e2c ()

./ldfile.c:630
#2 0x0000aaaae70d50b8 in main (argc=<optimized out>, argv=<optimized out>)
at ./ldmain.c:288
(gdb) disassemble
Dump of assembler code for function e843419@0011_00000103_e2c:
=> 0x0000aaaae70f20e8 <+0>: 00 00 00 00 .inst 0x00000000 ;
undefined
0x0000aaaae70f20ec <+4>: c7 ff ff 17 b 0xaaaae70f2008
<ldfile_add_arch+48>
End of assembler dump.
Current version 2.26.20160125+Atmel3.6.2-2 seems not affected anymore.
Kind regards,
Bernhard
