Ticket #184 (closed defect: fixed)
SHP: Issue when using the expression function INSTR in a filter
|Reported by:||thomasknoell||Owned by:||thomasknoell|
This error is caused in a SHP feature reader due to the assumption that the dynamic cast of an expression always returns a certain result. Therefore, the resulting pointer is used without checking for NULL and hence causes an issue if - like in the case that resulted in this ticket - an expression function is used in a filter.
