Bug #: 51565
Summary: fastcall in array of method pointers: internal
compiler error
Classification: Unclassified
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: a...@kent.ac.uk
Created attachment 26099

Preprocessed source (15 lines)
The attached program (presumably illegal) attempts to insert a pointer to a
class member function into an array of such pointers. However, the inserted
function has the fastcall attribute: this causes an internal compiler error:
> gcc -v --save-temps -c -Wall bug.cpp
Using built-in specs.
