System: Linux pluto 2.4.18-10 #1 Wed Aug 7 11:39:21 EDT 2002 i686 unknown
Architecture: i686
<machine, os, target, libraries (multiple lines)>
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.2/configure --with-local-prefix=/usr --enable-threads --enable-version-specific-runtime-libs --enable-languages=c,c++
>Description:
When I try to assign the address of a static class member function to a non-static member function pointer, the compiler correctly emits an error message (this is an illegal pointer assignment), but the line number that's specified in the error message identifies the line that's just below the line that contains the actual error:
/* n */ Line 'n' has the bogus pointer assignment
/* n+1 */ This is the line the g++ error message id's
And for some strange reason, g++ 3.2 also emits an "unused variable" warning for line 'n' (the line that has the bogus pointer assignment) -- see the attached code sample.
