I know.  Another thing I forgot to mention is that if my client exits 
before my server does, there's no crash either.  Also, if I follow the 
crash on gdb, the result is:

Thread 1 "mrViewer" received signal SIGSEGV, Segmentation fault.
__GI_getenv (name=0x7fffebd92f7b "UTLS_NO_EXPLICIT_INIT") at getenv.c:84
84Â Â Â  getenv.c: No existe el archivo o el directorio.

I tried using GNUTLS_NO_EXPLICIT_INIT in my environment but the crash 
happens nevertheless.  If I try it with valgrind, it says the invalid 
read 2 crash happens in gnutls or in some std::locale call.
