fatal signal 11

[cfk at pacbell.net]

I downloaded the latest wine from the cvs site and ran its
./tools/wineinstall. It ran for quite a while and croaked on
/wine/server/semaphore.c. Basically, gcc says "Internal compiler error:
program cc1 bog fatal signal 11". The compiler is 2.91.66 (aka egcs-1.1.2
release) and compiles other programs including 2.4.1 & 2.4.2 Linux kernels
just fine. I am puzzled what 'fatal signal 11' may mean. Can anyone offer a
suggestion for a course of  investigation.
