W2 crashes because of a syntax error in the textual input.

[Juergen Reuter]

WHIZARD 2 seems to incorrectly parse the input file.

When the code is generated for the first time, WHIZARD runs through. Afterwards one gets the error message above.

input file triggering the problem. I'm not sure whether newline really is an issue here.

Thanks to Sebastian Schmidt for this report.

Obviously this error is triggered by "show(cuts)" which does not exist. But this should be caught somehow.

With gfortran and 128 calls the integrations seem to run, with 127 calls

OK, delete the last line it belongs to Bug Report #91. I was too tired yesterday so this error occured.

Two points:

• This is indeed a syntax error. The lexer should provide more information about where this occurs (for any syntax error). However, this is no bug.

• show(cuts) should be implemented. As long as I have no pretty-printed output of expressions, the program can at least print the evaluation tree.

[kilian]

The first problem is reformulated as bug #93. The second problem is solved by [1322], but the implementation has the problem that the output is the parse tree (the only available info since cuts are compiled only when they are used). This is very verbose. I reformulated this as bug #94 and close the current one.
