Probable Bug

[David N. Williams]

I'm using egcs 2.91.66 on a PowerMac G3 under YellowDog Linux
Champion Server 1.1.

Here's the complete source in the file bug.c:

register int TOS asm("r26");
void threehundthou(){
 TOS = 300000;
}

Here's the result of compiling:

[hatforth]$ gcc --version
egcs 2.91.66
[hatforth]$ gcc -O2 -c bug.c
gcc: Internal compiler error: program cc1 got fatal signal 11
[hatforth]$ gcc -O1 -c bug.c
[hatforth]$ 

The problem occurs at -O2 and -03, and not at -O1.

Using a number in the signed, 16-bit range instead of 300,000 causes
no problem at any -O, and the .s output with -S is then correct.

Is this a bug?
