    Description

      The code that I will attach crashes qmlscene when compiled against Qt declarative release branch when compiled on debug mode and running under i386.

      Notes:

      • On release it works
      • If compiled in debug mode but we remove manually the O2 from the Makefile[s] it works
      • On amd64 it works
      • Run with QV4_NO_REGALLOC=1 works
      • Run with QV4_FORCE_INTERPRETER=1 works

      As requested by Erik Verbruggen I'm attaching the disassembly and some gdb backtrace too
