While compiling some heavily templated code using member variable pointers, g++
crashes. g++ is standard version installed with ubuntu hardy.
Changing line 49159 of js.ii from (self->*func)(a1, a2, a3); to
self->*func(a1, a2, a3); removes the ICE (however due to an (unresolved) bug in
my program on the program will fail to compile with "error: must use â.*â
or â->*â to call pointer-to-member function in âfunc (...)â" (which to
my understanding I am using ->* correctly, but obviously I'm not).
Compiled with: g++ -v -save-temps -Iinclude -I/usr/include/CEGUI -O3 -W -Wextra
-g -pg -c -o js.o js.cpp
gcc appears to be in the process of identifying the line number of my error
during the crash. it suggests it's on include/jswrap.hpp:283, but it is in
fact due to code on line include/jswrap.hpp:91 (aka js.ii:49159) which is
called by code on include/jswrap.hpp:283.
The crash appears reproducible in this exact one case, and can be removed/added
by changing the ()'s, and nothing else on the machine appears to be having
issues, so I don't think it's hardware related.
gcc diagnostics:
$ g++ -v -save-temps -Iinclude -I/usr/include/CEGUI -O3 -W -Wextra -g -pg -c -o
js.o js.cpp
