Bug ID: 95572
Summary: lto1: internal compiler error: in lto_input_tree_ref,
at lto-streamer-in.c:370
Product: gcc
Version: lto
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org

Test case
The version used by GCC is 7.3.0.
Only under the O0 option, ICE will appear, and O1+ will not report an error.
When I use the riscv compiler,the following ICE will be reported:
riscv32-unknown-elf-gcc vla-16.c -lm -o ./vla-16.exe -flto
In function 'f5':
lto1: internal compiler error: in lto_input_tree_ref, at lto-streamer-in.c:370
0x55b22e6f8b48 ???
../sysdeps/x86_64/start.S:108
