Increase crash handler buffers to 2048 bytes

1b43368ee044f0bb5469518fb3dee37ec177e780 · Claude · Jan 22, 2026 06:53

Further increased command buffer sizes in the DEBUG crash handler
to completely eliminate -Wformat-truncation warnings.

Changes:
- cmd buffer: 1536 → 2048 bytes (line 91)
- gdb_cmd buffer: 1536 → 2048 bytes (line 118)

This ensures sufficient space for exe_path (max 1023 bytes) plus
command text and pointer formatting, with comfortable margin.

Debug build now compiles with zero warnings under all strictness flags.
