There is a long discussion about this at

http://compgroups.net/comp.lang.c++/isn-t-std-string-npos-an-integral-constant/1043674

There are a couple of interesting explanations offered, including
allegations of an STL implementation bug, but no final resolution (and
the explanations may not apply to our specific case).

Suggestions:

1) Try moving String::npos initialization into String.cc.

2) If #1 alone does not help, try #1 with casted -1 instead of npos.

HTH,
