Subject: egcs g++ has optimizer error

Date: Mon, 27 Apr 1998 10:22:18 -0400

Package: g++
Version: 2.90.27-0.7

When trying to compile using c++ and -O2, I get errors in some very
trivial cases.

===============================================================================
class Pointer {
public:
    void    malloc(unsigned size, const void* memory=0);
};


class DPointer {
    Pointer*    dPtr;

public:
    void    malloc(unsigned size)
            { dPtr->malloc(size); }	// line 12
};
-------------------------------------------------------------------------------
c++ -O2 -Wall egcs-bug.cc -o /dev/null
egcs-bug.cc: In method `void DPointer::malloc(unsigned int)':
egcs-bug.cc:12: Internal compiler error.
egcs-bug.cc:12: Please submit a full bug report to `egcs-bugs@cygnus.com'.

Compilation exited abnormally with code 1 at Mon Apr 27 10:18:13
===============================================================================

If I remove the "-O" option, then it compiles okay and runs fine.

I tried with 2.90.28-0.1 (egcs-2.90.28 980423 (egcs-1.0.3 prerelease)).
With that version, the error also occurs with -O.

It does not occur when you use a different name than "malloc" (say "mall).

This problem appears to be fixed in the latest snapshot of egcs.

These bugs were no longer reproducable with the earlier pre-1.1 snapshots, 
so they should be fixed in Matthias' recent upload.

I'm closing them,
