Segmentation fault #9

Closed mohit162009 closed 6 years ago

mohit162009 commented 6 years ago

Hello,

Thanks for all the solutions, Its working now well.

But for vhdl files having ~1000 lines , I am getting the segmentation fault. I am not really sure why is this happening. Could you please help me here.

Nic30 commented 6 years ago

Hello, can you provide example input file please?

mohit162009 commented 6 years ago

stcu_integr_pkg.txt Hello, Please find attached sample file.

Nic30 commented 6 years ago

Hello, can you send how did you exactly get that segfault? I tried to parse that file you have send me and it seems to be working. I do not have python recompiled with valgrind support so I can not confirm that there is nothing wrong.

Does it happen every time or just sometimes?

mohit162009 commented 6 years ago

Hello, I am trying a lot of things, For some files if I remove package body, it works. Sometimes I have to remove constant arrays and sometimes few function I am not able to find out the exact reason and I am not sure what factors are causing this.

mohit162009 commented 6 years ago

Does the tool do any processing of vhdl file also apart from parsing, Such as if a function is called but not defined etc, Just thinking whether this can be an issue.

This is the segmentation fault message:

<< Job finished, querying job status ... >>

I switched to bsub to get more RAM, I have also tried installing hdlConvertor in python and also downloaded and built it locally, Both ways it fails.

I also tried valgrind and this is the output:

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

I have googled a lot about this and I have found multiple times that Segmentation Fault can happen if C code is inserting a NULL element into a PyList_Object, Is there something like this in your project?

Nic30 commented 6 years ago

Yes, there are 3 places (grep -R "PyList_New"). But now I see I forget to increment reference on array values and they can be automatically deallocated under certain conditions. (now it is fixed)

Errors you see in valgrind, are not real, valgrind does not understand python code due optimizations. https://stackoverflow.com/questions/20112989/how-to-use-valgrind-with-python

And when I ran with the file for which I was getting segmentation fault, Now I get this

Problem is combination of python3.5 and gcc 5, at leas I know where to search

Nic30 commented 6 years ago

58fa4f4c21ed95ec29e2c8ccb88f059c071c3bca fixed it, there were wrong deallocations and _ in bitstrings were not working under python 3.5. Try if it works for you, it works on Travis.

Helo, can you confirm that there is no issue anymore?
