Description Babu Arunachalam 2002-02-06 17:37:15 EST

Description of Problem:

The version of linux being used is 2.4.7-10smp.

gcc3 and gcc generate an internal compiler error for a class definition which 
includes nested structures and classes.  I have included the source files 
needed for compilation. Please copy them and run gcc.

Version-Release number of selected component (if applicable):

gcc3


How Reproducible:

Every time.

Steps to Reproduce:
1. Copy pasted files r.h, oops_rt.h and r.cpp
2. g++ -g r.cpp -I. -o r.o
3. 

Actual Results:

In file included from r.cpp:26:
r.h:6282: Internal compiler error in tree_low_cst, at tree.c:4325
Please submit a full bug report.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.

Expected Results:

Successful compilation.

Additional Information:

Please find attached files oops_rt.h, r.h and r.cpp

Comment 4 Jakub Jelinek 2002-02-07 08:57:37 EST

I agree gcc should not ICE on this.
Simplified testcase is:
struct A
{
};

struct B : public A
{
  char b[0x10000000];
} e;
The problem is that some C++ class layout routines store temporarily structure sizes
in HOST_WIDE_INT integer variables (this is normally 32-bit on IA-32) and the
structure sizes are in bits, so the above means gcc cannot fit the structure
size into signed 32-bit integer.
Quick workaround is to recompile gcc so that it will use
-DHOST_WIDE_INT=long\ long -DHOST_BITS_PER_WIDE_INT=64
(or, even better, don't build such huge classes).

Verified ok in g++ 3.2
