Can you provide more details about your compilation environment? Includes IDF version. Because I haven't encountered this problem.

I just set the optimization level to -O2, it build failed on window11 or linux on wsl2 i use idf 5.2.2 [cid:28f6a9bd-bcc2-4e86-adc5-ea2ccf3fbff2] [cid:9074a57e-8c89-4442-842a-264d462017cf]
