tlug: gcc bug in SlackWare 3.3

["J. David Beutel" <jdb@example.com>]

I am a most unhappy camper.  When recompiling pine 3.96, I get:

	cc: Internal compiler error: program cc1 got fatal signal 6

on SlackWare 3.3 (kernel 2.0.30, gcc 2.7.2.2).  I've looked on
dejanews for bugs in these 3 platforms, but haven't seen anything
like this.  I want to recompile so I can try a Japanese localization.
Can someone suggest an approach?  Has someone been able to recompile
their pine on this platform?

Details follow:

For pine 3.96, I started with the source from SlackWare 3.3
(which I am running on a newly-installed laptop, kernel 2.0.30),
with and without the patches from SlackWare, and even the pine 3.96
source from the Japanese localization site (ftp.noc.titech.ac.jp
/pub/tmp/aki/pine/) with and without its own patches.  So, yes,
the problem seems to be with the compiler itself (gcc 2.7.2.2)
or my system, which are both straight from the SlackWare 3.3 install.
(I haven't even rebuilt my kernel.)  I get the same problem both
before and after installing JE.  The pine that came precompiled
with SlackWare is also 3.96, and works fine (I'm using it now),
so there's at least one inconsistancy.  The bug occurs only and always
when compiling mailindx.c (both with and without optimization):

cc: Internal compiler error: program cc1 got fatal signal 6

Signal 6 is SIGABRT, so I presume that cc found an error and then
killed itself (not vice versa), but I would have expected a
better error message in that case (like from an assert(), including
the source file and line number).  The cc1 core file stack trace is:

(gdb) bt
#0  0x40077f61 in __kill ()
#1  0x4004407d in gsignal ()
#2  0x806e900 in free ()

#10 0x80637a2 in free ()
#11 0x8065cf2 in free ()
#12 0x8048f5e in free ()
(gdb)

The mailindx.c file has 4350 lines, so I haven't tried using
brute force to isolate the trigger.

I haven't compiled many other programs on this system, but this is
the only case I've seen.  I have had no problems compiling earlier
versions of pine on earlier versions of Linux on other hardware.
