ASAN consuming 100 CPU and RAM which leads to failure of ASAN every time, seems like timeout issue.

Current configuration:
32 GB Ram, I7 processor, 1 TB HD
OS: Ubuntu 16
ASAN Option: "report_objects=1

This information is not sufficient for us to help you.
Ideally, please provide a reproducer.
Failing that, show the stack trace where the application is stuck and/or show the 'perf' profile.

[tejas3]

what do you mean by reproducer ?
currently using clang compiler

[kcc]

We can not fix a problem w/o being able to reproduce it, or at least to get some idea of what's going on.
The better and the smaller is the reproducer, the more chances are that we will be able to fix it.

[tejas3]

okay, got it..
Could you please help me with some pointer to look?
I think it is timeout issue.

[tejas3]

please suggest some ASAN flags by which we can track this issue

[kcc]

start with

• run under gdb, collect several stack traces `

ctrl-c
bt
c

• run under perf

perf record ./a.out
# ctrl-c after some time
perf report

send the results here.
