I just got this when running "make -j2 bzImage" in a stock 2.4.7 kernel source tree on a dual-processor machine: gcc -D__KERNEL__ -I/usr/src/linux-2.4.6/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -c -o svcsock.o svcsock.c svcsock.c: In function `svc_recv': svcsock.c:876: Internal error: Segmentation fault. Please submit a full bug report. See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions. make[3]: *** [svcsock.o] Error 2 I've got gcc-2.96-94. I tried it again, and it compiled just fine the second time. I realize that may mean that I've got a problem with my RAM or something, but I've haven't seen any such problem with this machine,a nd all the mamory in it has been in it for at least six months, so I'm suspicious of that explanation. I thought I should report the problem even though I can't duplicate it, in case other people might be seeing similar problems and it's useful for you to know how much it's happening.
There is nothing that can be done about non-reproduceable bugs like this. It is most certainly hardware or some kernel issue, gcc is quite deterministic program.
