Weird log info while compile AOCX on quartus prime pro 19.1 for a10 board

Hi inteler:

It appear weird log info while compile AOCX on quartus prime pro 19.1 for arria10 board

environment:

OS:centOS7.5

environment: Quartus prime pro 19.1.240

board: A10gx

when the Batchsize=8, it's OK, no problem, while batchsize=32(DSP utilization about 64%) or 47(DSP utilization about 99%), other logic element is below 50%, it shows the following info, Anybody can help me , or give me suggestion ??

Thanks in advance!

Compiler Command: aoc -v -board=a10gx -l ./bin/dot_product_efi.aoclib -I /home/iot/work_example/work2/meiyang/dotProduct/inc ./device/sim.cl -o ./bin/sim.aocx -report

terminate called after throwing an instance of 'std::bad_alloc'

what(): std::bad_alloc
