Hi,

I'm hoping you folks can help. A couple of weeks ago, I built/installed
rsyncrypto-1.12. I tried it out and it seemed to work as advertised.

I put it down for a couple of weeks and tried it out again today... now
I get seg faults and core files. Yes, several libraries and a kernel have
been updated, but I have tried re-compiling and re-installing... this has
not helped (much).

As far as upgrades, among others, I noticed that I went from openssl-0.9.8b
to openssl-0.9.8e.

There's a bunch of entries in the stack trace that doesn't have useful
info. Any idea on how to get the info?

Any hints/suggestions would be appreciated.

Thanks.

I also ran strace and here is the tail end:

The core seems useless. The strace as pasted is also useless. Please run with -f and -o, and send me (private, after compressing it) the output.

Also, which OS, if Linux, which distro, and which version. In particular, what versions of openssl and argtable.

Thanks,
Shachar
