           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

C source code

The attached C code seems to ice on flag -O2.

$ ../results/bin/gcc -c -w -O2 bug654.c
destDir/testFile.289.c: In function ‘func_10’:
destDir/testFile.289.c:11479:1: error: invalid types in nop conversion

destDir/testFile.289.c:11479:1: internal compiler error: verify_gimple failed
0xcf360f verify_gimple_in_cfg(function*, bool)
        ../../trunk.git/gcc/tree-cfg.c:5482

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