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

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.
