Summary: [7 Regression] ICE when compiling
libquadmath/printf/printf_fp.c with -fsanitize=address
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer

Preprocessed file
Compiling libquadmath/printf/printf_fp.c with -fsanitize=address gives the
following ICE:
% gfc ~/Desktop/printf_fp.i -fsanitize=address -c
../../../work/libquadmath/printf/printf_fp.c: In function
'__quadmath_printf_fp':
../../../work/libquadmath/printf/printf_fp.c:127:1: internal compiler error: in
asan_expand_mark_ifn, at asan.c:2716
../../../work/libquadmath/printf/printf_fp.c:127:1: internal compiler error:
Abort trap: 6
The code compiles with revision r240271 (2016-09-20), but not with r241924
(2016-11-07) and gcc has to be configured with --enable-checking=yes. The
culprit could be r241896.
