            Bug ID: 92421
           Summary: ice in inline_small_functions, at ipa-inline.c:2001
           Product: gcc
           Version: 10.0
            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 47198
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47198&action=edit
gzipped C++ source code

For the attached C++ code with recent gcc trunk and compiler flag -O3,
does this:

$ /home/dcb/gcc/results/bin/gcc -c -O3 /tmp/q.ii
during IPA pass: inline
chewing_large_table2_kyotodb.cpp:426:2: internal compiler error: in
inline_small_functions, at ipa-inline.c:2001
0x8b15f7 inline_small_functions
        ../../trunk/gcc/ipa-inline.c:2001
0x8b15f7 ipa_inline
        ../../trunk/gcc/ipa-inline.c:2616
0x8b15f7 execute
        ../../trunk/gcc/ipa-inline.c:3024

I'll have my usual go at reducing the code and finding a revision range.
