Describe the Bug

i'm using an old macbook, which os version is 12.7.6 (21H1320). when i upgrade wrangler from 1.16 to 1.19, then the problems shows as below:

dyld[934]: Symbol not found: (__ZNSt3__122__libcpp_verbose_abortEPKcz) ..../@cloudflare+workerd-darwin-64@1.20250525.0/node_modules/@cloudflare/workerd-darwin-64/bin/workerd **Expected in: '/usr/lib/libc++.1.dylib'**

i'm using astro with cloudflare, i tested versions of "@cloudflare/workerd-darwin-64", i confirmed that, 1.20250520.0 is last version that does not have the problem.

please fix this bug.

Please provide any relevant error logs

the bug is with the "@cloudflare/workerd-darwin-64" lib, not the "wrangler" lib. please check the change log. it may caused by the upgrade of llvm from 18 to 19.

Hi @taojoe, I've transferred the issue to the workerd repository since this seems clearly a workerd issue to me, hopefully someone here will be able to help 🙂
