node hangs up on SmartOS with -O(>1)

[shigeki]

The node of Release build which is compiled with -O3 on SmartOS hangs up by the following script.

[node@ohtsu /var/tmp/node]$ cat ./test.js
var obj = {f: function(){}};
console.log(obj);
[node@ohtsu /var/tmp/node]$ ./node_O3 -v
v0.7.6-pre
[node@ohtsu /var/tmp/node]$ ./node_O3 ./test.js
^C[node@ohtsu /var/tmp/node]$

Note that node_O3 is the binary compiled with -O3 as defined by 'cflags': [ '-O3', '-fdata-sections', '-ffunction-sections' ] in common.gypi

I tried to test it on two types of kernels below but the issue still exists in both.

Server on no.de
$ uname -a
SunOS ohtsu.no.de 5.11 joyent_20110802T190624Z i86pc i386 i86pc Solaris
Server on node-ninja.com
$ uname -a
SunOS ohtsu.local 5.11 joyent_20110922T212927Z i86pc i386 i86pc Solaris

When I compiled node with not -O3 but -O, it works fine.

[node@ohtsu /var/tmp/node]$ ./node_O ./test.js
{ f: [Function] }

I'm not sure the reason, however, the workaround is to change the optimize option -O3 in https://github.com/joyent/node/blob/master/common.gypi#L43 into -O as

'cflags': [ '-O', '-fdata-sections', '-ffunction-sections' ],

Due to this issue, "make test" always hangs up in SmartOS in test/common.js

Yes, it's a known issue. new Error('').stack also hangs with release builds, for example. What's odd is that V8 seems to work okay when built standalone but enters an infinite loop when compiled into Node. Needs further investigation.

@bnoordhuis Thanks for reply Ben. I missed to tell you the version of gcc which was 4.5.2 on both no.de and node-ninja.com
FirstServer Inc of node-ninja.com. in Japan has provided me with a new SmartOS server which has new gcc (4.6.1) and I've found this problems completely solved.
So this issue may caused by using the old version of gcc and I made a patch b478b46 to check its gcc version and set its optimize level. I know this fix is very ad hoc and I would like to have your comment on this.
