# To avoid issues with Python version conflicts, or changes in environment

# over time on the OSS-Fuzz bots, we use pyinstaller to create a standalone

|
# required to keep fuzzers working properly in OSS-Fuzz.

|
# test case reproduction. Since this helper script is what OSS-Fuzz will

|
# actually execute, it is also always required.
|
|
# NOTE: If you are fuzzing python-only code and do not have native C/C++
|

# extensions, then remove the LD_PRELOAD line below as preloading sanitizer
|
|
# library is not required and can lead to unexpected startup crashes.
