Build with llvm-gcc-4.2

7.3.1168 works fine
7.3.1184 works fine

There are some changes to the regex engine.

7.3.1193 crash
7.3.1214 crash

That's definitely all for today,
I'm gonna watch football:-)

And another one:

Xcode 3.2.6 (The last version compatible with MacOS 10.6) comes with regular 
gcc 4.2.1 and

llvm-gcc-4.2 --version
i686-apple-darwin10-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) 
(LLVM build 2335.6)

With

./configure CC=llvm-gcc-4.2

the resulting Vim 7.3.754 does not crash.

I'll build 7.4a9 probably tomorrow.

Another datapoint:

I build Vim 7.4a9 on MacOS 10.8 with

gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) 
(LLVM build 2336.11.00)

No problems here.

On 10.6 I have

gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

I downloaded snapshot 66 which is Vim 7.3.754 and it doesn't crash.

I rebuild Vim 7.3.754 with my current compiler and it crashed.

Any idea where to look?

The last Xcode update was in March 2011

That was before snapshot 66 was build
(2010 Aug 15, compiled Dec 13 2012 00:07:34)

Looks like recursive use of addstate().  Does it run out of stack?
I don't know what _sigtramp is.

Could be a bug in the regexp engine.
