hi all
i meet a problem in gdb helgrind on x86-64/Linux take a example:
$ gdb /home/ykq/datarace/target/bin/valgrind
(gdb) handle SIGILL SIGSEGV nostop noprint
(gdb) b hg_instrument
(gdb) run --tool=helgrind ./a.out
===================
and then, in the hg_instrument function
(gdb) n
0x0000000038011d52 in hg_instrument (closure=0x40336be80, bbIn=0x3a6f6f10,
layout=0x383b6500, vge=0x40336be60, gWordTy=Ity_I64, hWordTy=Ity_I64)
at hg_main.c:3617
3617 {
(gdb) n
Warning:
Cannot insert breakpoint -8.
Error accessing memory address 0x3ec062fe70: Input/output error.
====================================================
who has the same experience and is there any problem in my gdb command?
Thx for our help!
