[MPICH] Bug in mpiexec_rsh.c builds wrong command line

[Reuti]

Hi,

one user of SGE noticed, that the daemonless smpd startup isn't  
working any longer in MPICH2 1.0.6p1 (http://gridengine.sunsource.net/ 
howto/mpich2-integration/mpich2-integration.html). After he and I  
digged in the code, we found in mpich2-1.0.6p1/src/pm/smpd/ 
mpiexec_rsh.c a bug. Line 472 must be changed from:

pExe += curLen;

to

pExe = process->exe + curLen;

Otherwise the string will not correctly be built, as curLen is added  
to pExe again, which is already pointing to a location somewhere in  
the middle of the string.
