I am using gcc-2.96-79 (+all related packages) on a RH 7.0 system
(glibc-2.2-5) and try to compile the gnustep-gui-0.6.7 package (obtained
from www.gnustep.org). The compilation exits with an internal compiler
error while processing the NSPanel.m file. 

Reproducible: Always
Steps to Reproduce:
1.get, rebuild and install
ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-make-0.9.2-1.src.rpm
2. get, rebuild and install
ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-base-0.9.3-1.src.rpm
3. get
ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-gui-0.6.7-1.src.rpm
4. rpm --rebuild gnustep-gui-0.6.7-1.src.rpm
	

Actual Results:  the compilation continued until a certain file (NSPanel.m)
was reached. At that point it stopped with an internal compiler error.

Expected Results:  Compile to the end!

This is the command line that called the gcc and the error message:

NSPanel.mi is created with -v flags -save-temps
Comment 2 Jakub Jelinek 2001-03-26 15:41:39 UTC 
A SUBREG_BYTE related bug.
Simplified into:
float d;
int e, f;

void foo (void)
{
  struct { float u, v; } a = {0.0, 0.0};
  float b;
  int c;

  c = e;
  if (c == 0)
    c = f;
  b = d;
  if (a.v < b)
    a.v = b;
}
at -O, -O2, have just fixed this and the fix will appear in gcc-2.96-80.
