Description

Description of the issue.

Am encountering a Segmentation fault (core dumped) error when running C benchmarks of mathematical functions.

Questions

Any questions for reviewers?

No.

Other

Any other information relevant to this issue? This may include screenshots, references, stack traces, sample output, and/or implementation notes.

The issue seems to be due to the benchmarks overflowing the default maximum stack size of 8 MB.
Increasing the stack size via e.g. ulimit -s 32767 causes the benchmarks to run properly.

We might want to rethink whether to allocate memory with malloc.

Reproduction

What steps are required to reproduce the unexpected output?

In order to reproduce this bug, do the following:

• From the top-level stdlib directory, run

make benchmark-c BENCHMARKS_FILTER=.*/dsqrt/.*

Expected Results

What are the expected results?

The benchmarks should run without issues.

Actual Results

What are the actual results?

The following are the actual results:
