Bug#623161: Internal error when building Executor Macintosh emulator
Package: gcc-4.5
Version: 4.5.2-9
Severity: normal
I was trying to compile the Executor Macintosh emulator, using the Git
repositories at
https://github.com/ctm/syn68k
https://github.com/ctm/executor
Compiling syn68k went without any obvious problems, but when compiling
executor itself, GCC printed the following error:
gcc -DHAVE_CONFIG_H -I. -I../src -I../src/include
-I../src/config/front-ends/sdl -I../src/config/os/linux
-I../src/config/arch/i386 -g -O2 -MT qIMVxfer.o -MD -MP -MF
.deps/qIMVxfer.Tpo -c -o qIMVxfer.o ../src/qIMVxfer.c
../src/qIMVxfer.c: In function ‘convert_pixmap_with_IMV_mode’:
../src/qIMVxfer.c:699:7: internal compiler error: in gimplify_expr, at
gimplify.c:6896
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
The qIMVxfer.c file is a nightmarish mess of pre-processor magic. I
tried boiling it down to a minimal test case and ended up with this:
int main() {
unsigned long int pixel;
((void)((1 == 2) ? ((void)(0)) : ((pixel) = 0)));
return 0;
}
I saved this as test.c, and got the same error when compiling that:
$ gcc test.c
test.c: In function ‘main’:
test.c:3:3: internal compiler error: in gimplify_expr, at gimplify.c:6896
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
GCC 4.6.0-3 prints an almost identical error. I haven't tried with
anything more recent than that. (I know I should try it with
gcc-snapshot, but it's getting really late here.)
Now, I'll be the first to admit that my boiled-down test case is utter
nonsense, but I figured that even rubbish like that shouldn't cause
internal compiler errors.
Sincerely,
Torbjörn Andersson
