Date: |
Thu, 03 Mar 2011 19:20:15 +0900 |
User-agent: |
Wanderlust/2.14.0 (Africa) SEMI/1.14.6 (Maruoka) FLIM/1.14.8 (Shijō) APEL/10.6 Emacs/22.3 (sparc-sun-solaris2.8) MULE/5.0 (SAKAKI) |
Steps to reproduce:
1. $ emacs -Q
2. M-x shell RET
3. M-: (setq default-process-coding-system '(dummy . utf-8-unix)) RET
4. C-u M-x shell RET RET
5. RET (in the *shell*<2> buffer)
Result:
Crash with SIGSEGV at process.c:5737
Vlast_coding_system_used = CODING_ID_NAME (coding->id);
