Description Douglas Mencken 2014-07-09 12:49:06 UTC
I cannot compile some LibreOffice .mm files using gcc-4.8.3 on OS X 10.5. Many of them fails with ICE when -O2 is used, but with -O(1) they compiles.

I cannot also compile .cxx files when -x objective-c++ is used on gcc line.

All of them ICE at the same spot: "in objc_eh_runtime_type, at objc/objc-next-runtime-abi-01.c:2792"

This one (vcl/osx/a11yselectionwrapper.mm) ICEs even with -O:

Also, there's builder.cxx (one of files which compiles after removing -x objective-c++ from line, but not with it):

In 4.9.1, it's not :2792 but :2793 ---

Now I know it's question about non-well-supported NeXT Objective C ABIs.

Will try -fgnu-runtime
Comment 6 Douglas Mencken 2015-10-02 01:05:58 UTC
Looks like I found the root of the issue ~
GCC ICEs when it meets C++ exception handling (try+catch)

$ cat main.mm
#include <Foundation/Foundation.h>
#include <iostream>

int main (void)
{
	try {
		throw 0;
	} catch (int & e) {
		std::cout << "caught" << std::endl;
	}

	NSString *name = @"GNUstep !";
	NSAutoreleasePool *pool;
	pool = [NSAutoreleasePool new];
	[pool drain];
}

$ g++ main.mm -o test.out -framework Foundation -lobjc
main.mm: In function 'int main()':
main.mm:4:5: internal compiler error: in objc_eh_runtime_type, at objc/objc-next-runtime-abi-01.c:2804
 int main (void)
     ^

This is similar to bug 35756 but since you have a different testcase I'll leave this open as a separate bug. Anyways, I think I have bad headers on my system, because my compiler chokes in that part:

And my ICE looks similar to the one I get in bug 57607 which also includes the c++ <iostream> header...

This error has now disappeared for me, so I can now confirm that I'm getting the same ICE that you originally reported:

$ /usr/local/bin/g++ 61759_main.mm -fpermissive -o 61759.exe -framework Foundation -lobjc
during GIMPLE pass: eh
61759_main.mm: In function ‘int main()’:
61759_main.mm:4:5: internal compiler error: in objc_eh_runtime_type, at objc/objc-next-runtime-abi-01.c:2793
 int main (void)
     ^~~~
libbacktrace could not find executable to open
Please submit a full bug report,
with preprocessed source if appropriate.

Running in gdb gives this backtrace:

Breakpoint 1, 0x00e60154 in internal_error ()
(gdb) bt

I'd need to rebuild gcc with debug info to get a better backtrace.
