Hi,

My name is Daniel and I'm spanish, so I'm sorry if you can't undertand something becouse of my low-level english.

Something stranger is happening to me with socket++ library and I don't know how to work on it.

I has a library called commands.so and the sslclient is and object of that library. sslclient creates an iosockinet object. Just when it creates that object, the program exits with a Segmentation fault error.

I compiled socket++ and my program with debug flag and all I see (and all gdb tells me) is that program recives a SIGSERV when it calls iosockinet constructor.

If I do the same on a separated file (main.cpp) that sslclient does, it works. But the most heavy is that my program runs under valgrind. I'm not an expert valgrind user so I don't know if it's normal (I don't think so).

I'm paranoid about the cause... I think it could happend becouse of the command.so library. If it heps, the iosockinet is created after sslclient object is created.

I'm working under gentoo and I tried the same come in 2 completly different gentoo with the same result, so I figure it's my fault. Once compute information is:

Thank you in advance,

Edit: code add, sorry. Includes are in sslclient.h.
