This has already been reported to Joy Kendall and may have already been
reported through other channels, since we discovered this a few days ago.
Anyway, we are running gcc-1.35 on a Sun3 with an fpa, which is running SunOS
4.0.3.
The following program causes a segmentation fault:
main()
{
char *s = "foo";
*s = 'f';
}
This one seems pretty significant. I have a hard time the compiler managed to
compile itself, and actually runs...

Furthermore, if you have old C programs that depend on this behavior, you can make gcc `do the right thing' by using the -fwritable-strings option.
