[aspectc-user] Segmentation fault in ac++

[Jens Schedel]

Hi,

with debug symbols in the ag++ i manage to determinate the point of the
segmentation fault in ac++:

In the compiled code i moved some global variables and types out from an
specific namespace. This produces the shown segmentation fault. But i
was not able to extract some piece of code leading to this segmentation
fault.

The segmentation fault is reproduceable with the following build
versions of ag++:
  * 206
  * 243
  * 245
  * 248
  * 257
  * 270

Regards,
Jens
