URL: https://github.com/apache/nuttx/pull/18563
In ESP32-S3 flat build with USER_HEAP mode, ROM strdup internally calls
malloc which may be mapped to a different heap than lib_free, causing
cross-heap allocation issues and system crashes.
This commit adds a new Kconfig option ESP32S3_DONT_USE_ROM_LIBC to allow
using NuttX libc instead of ROM newlib functions. When USER_HEAP mode is
selected, this option is automatically enabled.
Fixes: 60ca804b56 ("esp32s3: Fix bug related to the PSRAM-allocated task
stack")

## Summary
*Update this section with information on why change is necessary,
what it exactly does and how, if new feature shows up, provide
references (dependencies, similar problems and solutions), etc.*
## Impact
*Update this section, where applicable, on how change affects users,
build process, hardware, documentation, security, compatibility, etc.*
## Testing
*This section should provide a detailed description of what you did
to verify your changes work and do not break existing code.*
*Please provide information about your host machine, the board(s) you
tested your changes on, and how you tested. Logs should be included.*
*For example, when changing something in the core OS functions, you
may want to run the OSTest application to verify that there are no
regressions. Changes to ADC code may warrant running the `adc`
example. Adding a new uORB driver may require that you run
`uorb_listener` to verify correct operation.*
*Pure documentation changes can just be tested with `make html`
(see docs) and verification of the correct format in your
browser.*
**_PRs without testing information will not be accepted. We will
request test logs._**
