[Issue 7293] dmd 2.057 segfault/crash - std.regex.match(string, string)

The usual practice is to mark things as fixed if they are fixed in the most recent github build, which naturally will be ahead of the latest release. I mark as "worksforme" things that were (apparently) recently fixed as part of another bug fix, and I don't have a specific commit to log what did the fix. In other words, this was an unrecognized duplicate of another bug. Which bug it was, I do not know, nor do I wish to spend a couple hours figuring out which one it was. Please reopen if a seg fault can be produced on this with the latest github version. I cannot reproduce a seg fault. I agree that if this is a phobos bug, it should go under a separate issue. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

On what DMD version? Note that yebblies is using a version that isn't even released yet. > No dmd seg fault. Changed to Phobos issue. So far, four of us have confirmed that the compiler IS segfaulting. This is definitely a bug in the compiler. It may have gone away by itself in 2.058, but this doesn't change the fact that the bug is there in 2.057. If the segfault has been fixed in 2.058, then mark it as such. If there is bad code in Phobos, this is a separate bug from the fact that the code crashes DMD. As such, it warrants a separate bug report. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

On win32 I get the following:
DMD v2.058 DEBUG
..\..\phobos\std\regex.d(6278): Error: malloc cannot be interpreted at compile
t
ime, because it has no available source code
..\..\phobos\std\regex.d(6278):called from here:
enforce(malloc(size),de
legate pure nothrow @safe const(char)[]()

}
)
..\..\phobos\std\regex.d(6449):called from here:

, __ctmp919).this(regex(re,""),input)
testx.d(4):called from here: match("","")
So it might actually be ice_on_invalid code... and also a phobos bug.

Please remember to:
- assign keywords as appropriate
- make summary lines specific to the bug
- change platform/OS to "All" if you witness it on something different from
what the reporter reported it on.
Even smaller testcase:
-
import std.regex;
auto m = match("", "");
-
