LLVM ERROR: SmallVector unable to grow.

[KatCe]

Hello,

with the following synthesis commands and the program (myfunc) below,

set-clock-period 8
compile --sharing  --buffer-algorithm fpl22
write-hdl --hdl verilog

I get the following error:

Performance analysis available, share functional units as much as possible while maintaining the performance...
dot: graph is too large for cairo-renderer bitmaps. Scaling by 0.373315 to fit
LLVM ERROR: SmallVector unable to grow. Requested capacity (4294967296) is larger than maximum value for size type (4294967295)
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
