It is not the question of the compiler, it is the CVS checkout date. The
problem is not there for me in the version checked out 05 May, problem
is there with the version from 17 June. Compilers and compilation
options the same.

Again: when PV is compiled in DEBUG mode nothing crashes. If compiled 
with gcc (but not icc) with RELEASE mode then crash. gdb's bet: "cerr << 
"hello world" << endl", the first line of my plugin's RequestData.
