## I ran into the same issue with ruby version 1.9.1-p429 using gcc 4.4.4. I read the comments in issue #2727, but think that it is not acceptable that the latest stable version of ruby cannot build with gcc 4.4.x now. Note: it’s not possible to build ruby without -O2 optimization because -O2 is hardcoded in configure.in if gcc is used, see the test for gcc in line 191 and the following setting of ${optflags}.

Why did you think it is impossible?

Try:

$ ./configure optflags=-O0 debugflags=’-g3 -ggdb’

and/or

$ make optflags=-O3
