[Inference] Infer: Program received signal SIGSEGV, Segmentation fault. But train model is OK about lightlda HOT 6 CLOSED

it is odd enough. your program cored at somewhere request mutiverso. however, it is nothing about mutiverso since all data including model stored at local buffer when inference.
can you please to show us the exact line number core dump happened？ i will try to help

hi, @hiyijian
Thanks for your time. the debug core information as follows:
Run till exit from #0 multiverso::lightlda::AliasTable::Build (this=0xe7da190, word=6, model=) at /home/tools/DMTK/lightlda_inf/src/alias_table.cpp:82
multiverso::lightlda::Inferer::BeforeIteration (this=this@entry=0xe7da530, block=block@entry=0) at /home/tools/DMTK/lightlda_inf/inference/inferer.cpp:53
Value returned is $2 = 0

looking forward to your reply.

I am sorry but can you share me with trained model and new/unseen docs data? I will try to reproduct it. I found that It's difficult to figure out the problem with core information.

from lightlda.

OK. How do i share the model with you?
can you give me your email?

Except data validity, the problem partly caused by a boundary condition check. @feiga has already fixed in commit 733a06c.
Thanks for your report
