[aspectc-user] Segmentation fault parsing a C++ header file

[Olaf Spinczyk]

Hi,

what about the parser configuration file (e.g. puma.config)? Do you have 
one? How did you generate it?

We tested to parse the code with 1.0pre1 and with the upcomimg 1.0pre2 
and there was no crash in both tests. We believe that the problem has to 
do with your execution environment.
