validation test failed/segmentation fault

[Jitendra Padhye <jitu@cs.umass.edu>]

Hi,

I just installed ns-allinone-2.1b3 on a solaris machine (SunOS 5.5.1
Generic_103640-08 sun4u sparc SUNW,Ultra-1), with gcc 2.7.2.1.

The installation went well, but the last validation test failed: 

===========================
*** ./test-all-session
Tests: Session1 Session2 Session3
Running test Session1
tracing
Segmentation Fault - core dumped
Test output differs from reference output
Diagnose with: diff test-output-session/Session1.test
test-output-session/Session1
Differences due to floating-point formatting are not significant.
Running test Session2
tracing
Segmentation Fault - core dumped
Test output differs from reference output
Diagnose with: diff test-output-session/Session2.test
test-output-session/Session2
Differences due to floating-point formatting are not significant.
Running test Session3
tracing
Segmentation Fault - core dumped
Test output differs from reference output
Diagnose with: diff test-output-session/Session3.test
test-output-session/Session3
Differences due to floating-point formatting are not significant.
Some test failed
validate overall report: some tests failed:
     ./test-all-session
===========================

Any idea what might have gone wrong? Has anyone else experienced this
problem before?

Thanks,
