IL code reproducing the bug
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.11)
Gecko/20080111 Firefox/2.0.0.11
The attached IL program never ends. It seems that the JIT produce an infinite
loop, even if the program itself does not contain any loop.
Howover, if you uncomment the ldstr/WriteLine at lines 50-51, the JIT produces
the right code and everything works as expected.
Reproducible: Always
Steps to Reproduce:
1.ilasm2 bug.il
2.mono bug.exe
3.ctrl-C to stop it :-)
Actual Results:
the program doesn't end
Expected Results:
the program should print 0
This is the broken mono version I got:
$ mono -V
Mono JIT compiler version 2.2 (tarball Thu Feb 5 11:12:49 CET 2009)
