I need more time to setup the environment for this issue. After reviewing, however, I found that here and here does not comply with alignment rule in Sparc. This two parts will cause bus error in Sparc, and they might be the cause of this issue.

I could run the test on Sparc environment for you :p

That's great.

But the current problem is, this issue is difficult to fix due to the following reasons:

• This is related to uhash.dat, so we cannot just change the binary format. And for this issue, changing binary format to align uint16_t requirement is the most easy way to fix.
• Use the save way to read unaligned data in Sparc require knowing endianness of the platform, so we might need to do endianness detection at compiling time or runtime.

Hi @kanru, please help to test this in Sparc, thanks.

from libchewing.

I can't connect to the sparc box right now.. I'll try again tomorrow.

I can confirm that 52831f4 builds fine on sparc (debian sid chroot) by executing ./autogen && ./configure && make .

Did you run the test suite? make check

Ah sorry, make check failed:

Is it possible to get the core dump? I want to know which line cause the bus error.

Too bad we have unaligned memory access in phrase. I need some time to implement this.
