SIGSEGV while trying to run memtrace & memval_simple from sample clients #6391
Description
I was trying to observe the Load and store of a simple cpp program. so get all the loads and store operation and their address where load and store happens and data in it. So came across dynamo rio. While i was trying to use the sample client memtrace_x86.c
which is libmemtrace_x86_text.so. I Received SIGSEGV.
using LINUX x86_64
The command ->. drrun -root /home/athbha01/dr_dynamorio/drio/DynamoRIO-Linux-10.0.19613 -c /home/athbha01/dr_dynamorio/drio/DynamoRIO-Linux-10.0.19613/samples/build_ath_track/bin/libmemtrace_x86_text.so -debug -- ./myprogram_test1
The code in myprogram_test1 is
int main() {
// int curr_var=444;
int *ptr =( int*) malloc(4);
printf("Address of the pointer ptr : %p\n", ptr);
*ptr = 444 ;
printf("Addition Operation");
*ptr = *ptr + 1 ;
printf("Division Operation");
*ptr = *ptr/ 2 ;
// int* m4=&curr_var;
// printf("Address of pointer ptr: %p\n", (int *)m4);
// printf("Address of the pointer ptr : %p\n",ptr);
printf("Value of the pointer ptr : %d\n",*ptr);
return 0;
}
So when i executed the command i got this segmentation error it apprently also gives segmentation fault when i simply have main(){}.

Please also answer these questions:
- What happens when you run without any client?
-> it works , it works for all other clients besides which is related to mem. like memtrace, memval. for rest it works. - What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)?
-> same error
Versions - What version of DynamoRIO are you using?
drrun version 10.0.19613 -- build 0
