Summary: ice in get_source_location_for_substring, at
input.c:1507
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

C source code
The attached C code, when compiled by recent gcc trunk and flag -O2,
does this:
$ ../results/bin/gcc -c -O2 bug406.c 2>&1 | more
during GIMPLE pass: printf-return-value
../mruby-source/mrbgems/mruby-sprintf/src/sprintf.c: In function
‘mrb_str_format

err
or: in get_source_location_for_substring, at input.c:1507

../../trunk/gcc/c-family/c-common.c:866
0xd79b95 substring_loc::get_location(unsigned int*) const
../../trunk/gcc/substring-locations.c:191
I'll have the usual go at reducing the code and identifying
a range of revisions for the error.
