Sage 3.4.1.rc1 on OSX 10.6

[mabshoff]

Hello folks,

I spend the evening fixing OSX 10.6 build bugs in Sage since we want
to be ready once it is release in a couple months. Since I am running
a development snapshot on my laptop I figured it would be good to have
a working Sage again locally. It only takes a couple patches to get
Sage to compile with

bash-3.2$ gcc -v
Using built-in specs.
Target: i686-apple-darwin10
Configured with: /var/tmp/gcc/gcc-5621.3~3/src/configure --disable-

host=x86_64-apple-darwin10 --target=i686-apple-darwin10
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5621) (dot 3)

Sage does start up, but there is a segfault at exit:

bash-3.2$ ./sage

I traced this to an oMalloc problem:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000019
0x04a5aa0c in Rational::~Rational () at omInline.h:69
69 omInline.h: No such file or directory.
in omInline.h

But I guess given there is also a still unresolved problem on OSX 10.5
in 64 bit mode this might be related.

Cheers,

Michael
