[Valgrind-users] Please check the dhat could run in the ELF32 mode in x86-64.

[Wuweijia]

Hi: I compile the code in x86-64 machine, and run dhat . it is ok.
The compile cmd: gcc -g -O0 main.c
The dhat cmd valgrind -tool=exp-dhat ./a.out


But I compile the same code in the same machine, but another compile cmd, and run dhat. It failed.
The compile cmd: gcc -g -O0 -m32 main.c
The dhat cmd valgrind -tool=exp-dhat ./a.out

I just compile same code into ELF32 mode.


The output as below:
DHAT: dh_main.c:756 (dh_handle_noninsn_write): the 'impossible' happened.

The valgrind version is 3.12.0

Does dhat support elf32 mode?
