Bug ID: 107044
Summary: internal compiler error: in
dump_possible_polymorphic_call_targets, at

Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org

Reproducer, taken from 483.xalancbmk in SPEC CPU2006
With the `riscv64-linux-gnu' target and the attached source I get an ICE:
during GIMPLE pass: fre
dump file: TokenFactory.ii.112t.fre3
TokenFactory.ii: In member function 'xercesc_2_5::Token*
xercesc_2_5::TokenFactory::getGraphemePattern()':

Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.

Preprocessed source stored into /tmp/ccZIsvk3.out file, please attach this to

with this compiler invocation:
$ riscv64-linux-gnu-g++ -fdump-tree-all -S -o TokenFactory.s -Ofast
--param=max-inline-insns-size=90 -march=rv64gc -mabi=lp64d TokenFactory.ii
GCC built with `-O0 -g' for the purpose of obtaining a reliable backtrace
only, the same ICE triggers with the usual `-O2' compilation.
NB this comes from the same program and is the same assertion as with
PR ipa/79931 and PR tree-optimization/80249.
