I apologize. Step 4 has changed to: sh Scripts/gcc-dev-cfg.sh in latest trunk. Secondly, I have upgraded to: gcc version 4.4.2 20091222 (Red Hat 4.4.2-20) (GCC) and in this version I can confirm that this is related to the optimization level. qmake's default configuration ends up adding "-O2" to the build options; if I manually change this to "-O0", the compilation completes in 4 seconds. This may be a duplicate of 531218. No dice. Using: gcc version 4.4.2 20100112 (Red Hat 4.4.2-24) (GCC) it still hangs on 'ImageVis3D_WindowHandling.cpp'. "-O0" is still a valid workaround. I'll also note that "-O1" seems to cause the issue as well. I guess I'll resurrect the gcc44-max-vartrack-size.patch, but this time with a 50000000 default instead of 5000000. That way it shouldn't trigger on reasonably sized testcases and will only trigger on these monsters. Please try gcc-4.4.3-4.fc12. I apologize for the delay. Compilation succeeds on a fresh+updated FC12 install (gcc-4.4.3-4). Thanks! I do get a: note: variable tracking size limit exceeded with debug insns, retrying without but from comments it sounds like this is by design. |
