Hello,
i too experienced this error in Java when i did
several swap evaluations in a row yesterday.
The code runs nicely several times and then throws the
"pure virtual function call" which crashes the JVM.
It always happens on "setEvaluationDate" in the Settings class.
I would be really happy to see this fixed, since it makes
QuantLib practically unusable in my scenario.
I will try myself, but i am far from being a SWIG expert.
Software used:
Windows 7 x64
QuantLib 1.0.1
SWIG 2.0.0
Java 1.6.0_22
QuantLib compiled with Visual Studio Express 2008
Best regards,
Henner Heck
