I am trying to track function call counts on a program I'm interested in. If I run the program on its own, it will run fine. If I try to run it with valgrind using the command seen below I seem to be getting a different result.
Command run:
Produces this input immediately, even though the execution is normally slow.
CodePudding user response：
valgrind has limited floating point support. You're probably using non-standard or very large floats.
CodePudding user response：
I'd say that this is more likely to be related to this issue. However to be certain you will need to tell us
- what compilation options are being used - specifically are you using anything related to AVX or x87?
- What hardware this is running on.
It would help if you can cut this down to a small example and either update this or the frexp bugzilla items.
