crash on readChan/writeChan
Source code:
http://www.seas.upenn.edu/\~lipeng/tmp/ghc_smp_bug.tar.gz
Compile using the latest Linux binary snapshot (ghc-6.5.20060223):
$ ghc -fglasgow-exts -smp Server.hs --make -o Server.bin
Run on a 2-way SMP machine:
$ ./Server.bin +RTS -N1
- ...
- ...
Server.bin: internal error: EVACUATED object entered!
Please report this as a compiler bug. See:
Aborted
Sometimes I get segmentation fault instead of the above error messages. 100% reproducable on 4 different Linux machines. This bug can be also reproduced using +RTS -N2 by slighly changing the source code. Also reproducable on an older version (20060205). Is it a bug or am I using GHC incorrectly?
