--- Comment #6 from Nidal Faour <nidal.faour at wdc dot com> ---
Andrew Pinski is right, after chasing this bug with the help of Andrew Burgess
in the file simple-object.c, calling the creat
outfd = creat (dest, 00777);
the creat function wraps the open function but do not pass open mode
and the fix mentioned by Adrew was as follow:
When opening output files for simple-object creation, we must ensure that the
file is opened in binary mode. Failure to do so causes file corruption, and
LTO failure on Windows targets.
libiberty/ChangeLog:
PR lto/88422
* simple-object.c (O_BINARY): Define if not already defined.
(simple_object_copy_lto_debug_sections): Create file in binary
mode.
