Subject: [Bug target/14457] New: ICE with simple c++ source
X-Bugzilla-Reason: CC

List-Id: <gcc-bugs.sourceware.org>

	3.4.0 20040303 generates ICE. But
	3.4.0 20040227 work fine.

Environment:
System: Linux namsh 2.6.4-rc2 #63 Thu Mar 4 21:18:27 KST 2004 i686 athlon i386 GNU/Linux
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: m6811-unknown-none
configured with: ../configure --disable-nls --target=m6811-elf --prefix=/usr/GNUHCS --program-prefix=m6811-elf- --with-gnu-ld --with-gnu-as --disable-shared --enable-languages=c,c++ --without-headers --with-newlib

How-To-Repeat:
Just do 'm6811-elf-g++ -o tmp.o -c t.cpp -m68hc12'.

The t.ii is:
    # 1 "t.cpp"
    # 1 "<built-in>"
    # 1 "<command line>"
    # 1 "t.cpp"
    class CKMCLink {
    public:
	void LinkDelete(CKMCLink**);
    private:
	CKMCLink *m_prev;
    };

    void
    CKMCLink::LinkDelete(CKMCLink **head)
    {
     if (m_prev == this)
     {
	 *head = 0;
     }
    }
------- Additional Comments From namsh at kldp dot org  2004-03-06 05:26 -------
Fix:
    If I do 'm6811-elf-g++ -o tmp.o -c t.cpp -m68hc11'. No ICE.
    If I use m6811-elf-g++ 3.4.0 20040227 with -m68hc12, No ICE.
