Indeed,
The problem is gone. Thanks a lot.

The culprit seems to be changeset f2ceaaf24796:

Hello,
I updated my default branch and I do the following:
mclient -lmal
\q
mclient -lmal
\q
After the second exit I get a crash in the mserver:
[New Thread 0x7fffdf7ac710 (LWP 19441)]
Program received signal SIGSEGV, Segmentation fault.

Similar problem if you do mclient -lsql
\q
mclient -lsql
The mserver crashes due to the same problem: Program received signal SIGSEGV, Segmentation fault.

Were there any changes in the client structure or in the initialization of the of the client threads?

PS: It does not happen in the Oct2010 branch.
