When I said "this is the default", I meant gcc-4.3.2 is the default compiler of Ubuntu-8.10. I did not mean that -O3 is the default optimization level when compiling Vim. Maybe that was confusing. In any case, I would expect -O3 to work. One of the most important optimization brought by -O3 is inlining of functions. And this is precisely the optimization which somehow breaks vim. You can build with -O3 by editing src/makefile, or by doing... make CFLAGS=-O3 Doing a google search, I found afterwards that it's not a new issue. It was already reported here with the same suggested fix: http://www.mail-archive.com/[EMAIL PROTECTED]/msg03320.html However, the above thread mentions that -fstack-protector triggers it, whereas I observe it with -O3 or with -O2 -g -finline-functions.
