Subject: [Bug c/101642] New: ice in decompose, at wide-int.h:984
Date: Tue, 27 Jul 2021 12:08:22 +0000 [thread overview]
Message-ID: <bug-101642-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101642
Bug ID: 101642
Summary: ice in decompose, at wide-int.h:984
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 51210
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51210&action=edit
C source code
The attached C code does this with recent gcc:
$ ../results/bin/gcc -c -O2 bug740.c
during GIMPLE pass: fre
netflow_v1.c: In function ‘Process_v1’:
netflow_v1.c:507:1: internal compiler error: in decompose, at wide-int.h:984

unsigned int, generic_wide_int<wide_int_storage> const&)

const&,
unsigned int)
../../trunk.git/gcc/wide-int.h:790
I will have my usual go at reducing the code and trying to spot a
range of git hashes where the problem first occurs.
