Segmentation fault
Jul 15th, 2010 at 7:44pm
 
Hello,

I am trying to run HYPHY on a large matrix (976x976) and am experiencing the following error before HYPHY aborts:

*** glibc detected *** /bin/hyphy/HYPHY/HYPHYMP: double free or corruption (!prev): 0x000000003e52b2d0 ***


I use this command to get by the error:

export MALLOC_CHECK_=0


However, although HYPHY will run, the optimization does not converge and crashes with a segmentation fault error.

The same exact code works perfectly with a 244x244 matrix and the optimization converges.

Is HYPHY able to handle such large matrices?  Is there anyway to get around these errors?

Hi Mike,

There should be no problem with a 944x944 matrix assuming you enough ram.
This must be a bug that I'd like to track down. Could you email the batch files that I would need to replicate the crash?
