panic(thread 1416): integer does not fit in destination type
oh no: Bun has crashed. This indicates a bug in Bun, not your code.

Analysis

• System Bun upgraded to 1.3.6 via bun upgrade, but Claude Code uses its own bundled Bun 1.3.5
• Bun 1.3.6 is available and may contain a fix for this issue
• High memory usage (6GB RSS) at startup suggests memory-related trigger
• Bun crash report link: https://bun.report/1.3.5/e_11e86cebmgEugogCw+kiM65ioJgqpmMCYKERNEL32.DLLut0LCSntdll.dll4zijBA0eNoFwcENACAMAsBVWM1ENHyosXzc3js53LyYxYYrWApkTHbkEZWRd/gBNAAPKQ

Suggested Fix

Update bundled Bun to v1.3.6+ in next Claude Code release.
