[Pw_forum] Problem with el-ph calculation: lambda.x run

[W2AGZ]

Last March, an issue running lambda.x was posted on the forum.here is the
direct URL link,
http://qe-forge.org/pipermail/pw_forum/2013-March/101264.html, reporting
various NaN errors generated during an 4.3.2 Example 7 script adapted for
graphene.  Was this issue ever resolved?  My personal experience with NaNs
has been that they usually reflect compiler issues, especially wrt IEEE
standards governing floating point formats.  However, I don't see anything
unusual in the lambda.f90 code.
