           Summary: DMD aborts with MALLOC_CHECK_ set
           Product: D
           Version: 1.040
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Keywords: ice-on-invalid-code
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: larsivar igesund.net


I don't know how common it is, but at least Ubuntu has a standard environment
variable called MALLOC_CHECK_ which typically is set to 2. When it is set,
memory allocations are checked (it can also be set to 3). However, with DMD
1.040 this causes an "Aborted" message. Setting MALLOC_CHECK_ to 0 makes it
work again.

I have tried to narrow down where it happens, but I seem to fail to get it much
shorter than the following (and it seems that Exception itself from object.di
may be involved):

class PlatformException : Exception
{
    this(char[] msg)
{
super(msg);
}
}
class AssertException : Exception
{
    this(char[] file, size_t line)
{
super("Assertion failure",file,line);
}
    this(char[] msg, char[] file, size_t line)
{
super(msg,file,line);
}
}
void setAssertHandler(int){
}

This is a regression in DMD 1.040

Also happens in dmd 2.025

When MALLOC_CHECK_ set to 1, I get the following message:

*** glibc detected *** dmd: realloc(): invalid pointer: 0x08d2c6a8 ***
Segmentation fault

 Perhaps, you may want to post it to bugzilla, instead?



I see that's not working now anymore, good to know. Anyway it seems Walter 
already solved it.

It's supposed to work, i.e. responding to the NG thread is supposed to
post to the Bugzilla as well.  It just stopped working a couple months
ago..

Yeah, I know. That's why I suggested to re-submit the post to bugzilla. I
actually like the way it is, it allows commenting the reports while
sidestepping the bugzilla. This is useful if your comment is worthless anyway.
Just like this one :)

I didn't know about MALLOC_CHECK_. It's a great feature, and I found the (off
by one) problem.
