Subject: segmentation fault of modpost

Hi,

I tried to build tip-tree with allmodconfig and ARCH=i386 on x86_64 machine.
And modpost caused segmentation fault like this:
modpost[23652]: segfault at 2b53bece3000 ip 00000000004030bb sp
00007ffffad8d260 error 4 in modpost[400000+d000]
# from dmesg

The commit of -tip tree is 64256eb8e9f8cd53100ee6142968df336c54eb32.

Is this problem already reported or solved?
If not, I'd like to solve this because I need to build all{mod,yes}config
kernel for testing readq/writeq of x86.

Thanks,
