The return of Internal compiler error.

[Antti S Lankila <alankila at cc dot helsinki dot fi>]

Hello, people

Short:
internal compiler error hit compiling libgtop-0.99.2 using 19990208 ss.

Severity:
Critical (meaning abortion of compile at the point).

Long:
Hmm... I guess it's about time I join the mailing list. Anyway,
I hit an egcs `internal compiler error' compiling libgtop-0.99.2 using
the latest 19990208 snapshot. I grabbed the libgtop from
ftp.sunet.se/pub/X11/Gnome mirror.

make[3]: *** [proclist.lo] Error 1

As always, it's reproducable any time typing make, cleaning filesystem
cache/buffers and such will not affect it so I'm convinced it's an
indication of some actual problem. Debugging stuff pasted from xterm

Which is sent to you along with this message.

I couldn't find a way to make that stuff compile just twiddling with
-g, -Ox options, so I substituted egcs snapshot with egcs-1.1.1 for a
moment which allowed me to stumble past the problem.

My setup is: P100, 48 MB RAM, kernel 2.2.2-pre2, glibc-2.0.112,
binutils-2.9.1.0.19a.

Cheers,

Antti
