Re: repeated try{} catch{}

Akira,

Your problem is caused by a defect in the CINT bytecode generator.

You can either run your script with the bytecode generator turned off like this:

root [0] .L except.C+
root [1] .O0 // Note: This is a capital letter O followed by the digit zero.
root [2] .x test.C

which has a large performance penalty, or you could modify your test.C script so it compiles by adding a #include "./except.C" at the beginning and then afterwards running it in root as a compiled script this way:

root [0] .x test.C+

The second option should be your preferred option, you gain the full error checking of the compiler and native code performance as as opposed to interpreted performance.

It would be a large effort to improve the CINT bytecode generator to support this code and we will not be able to devote effort to doing so at this time.
