Prerapsearch Aborted (core dumped)

[Ruth28]

Hi,
I am trying to ru
n prerapsearch on the NCBI viral dataset.
I have tried
prerapsearch -d viral.1.protein.faa -n test2
and
prerapsearch -d viral.1.protein.faa -n test2 -s 10

And both times I get the same error message, as follows:

ow building hash file
hash file saved to file test2

Any suggestions on how to prevent this from happening would be greatly appreciated.

Thanks,

This following line:

*** glibc detected *** prerapsearch: free(): invalid pointer: 0x00007fff44c7b320 ***

... suggests that prerapsearch is trying to free memory (man 3 free) that it is not allowed to free, resulting in a segmentation fault.

You need to compile with debug information enabled, e.g. -g option to gcc, not strip this debug information, and rerun your command line with this debug build. This is required to find the exact location in the source code where the bug occurs.

Then you need to inspect the generated core dump, e.g. via gdb prerapsearch core.PID and input bt in the gdb command line to get the full backtrace.

Hi,
I'm helping Ruth out. So I recompiled prerapsearch, and ran the debugger on it. I got this back - do I need to install the extra yum debuginfo install (I tried, but had some problems re RHEL and its repository):
