exp-sgcheck verbose output
First of all, thanks for maintaining/developing valgrind, such a great tool!
I tried for the first time to use the sgcheck tool, but the tool cannot run my
(any?) executable. The error is
exp-sgcheck: sg_main.c:2332 (sg_instrument_IRStmt): the 'impossible' happened.
This issue has been reported on the mailing-list earlier this months. Someone
gave instructions to provide more debugging info:
https://www.mail-archive.com/[email protected]/msg06477.html
I attached the output of the second command, that is
valgrind --tool=exp-sgcheck --trace-flags=11000000 --trace-notbelow=1564
/bin/ls
Some additional info:
