Got Segmentation fault When compiling bit larger projects about hhvm

[ivanjovanovic]

I have the same problem when I try to compile Wordpress on CentOS 5.4 64bit
Although compiling works on Ubuntu 9.10
I suppose it is the version of boost that is making problems, but I'm not sure.
My boost version is 1.38 on both CentOS and Ubuntu.

I have the same problem, traceback with debug symbols:

0x6F6C672F73797344 is obviously garbage, the string "Dsys/glo" to be exact.

It does not crash when compiled with -O0 -g (set by editing CMake/HPHPSetup.cmake). I should probably mention that my gcc version is gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-46).

[scottmac]

We're only supporting GCC 4.3+ now, can you give that a test.
