Title:
mcs optimises falsly code out in "if ( ... &&false)
Status in The Mono .NET development environment:
Fix Released
Status in “mono” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: mono-mcs
My collegue Martin Zaworski found a misbehaviour, we have then tracked it
down to following:
if (foo++ && false) {
} else {
//foo isn't incremented
}
So, in an conditional statement, with &&false, the left hand side doesn't
run(or gets compiled), no side effects are
executed. Also no function() can be called inside there).
Works also with assignments, optimisation switches don't matter.
Microsoft csc.exe is void of that problem
Package: mono-mcs 1.2.4-6ubuntu4
Also affected is the current svn version (21/9/2007).
We have here now untrusted compiled binaries, unless it's verificable, that
this kind of source coding isn't used,
they have to be recompiled with a fixed version of the compiler.
