Bugzilla Bug 88286

After installing vuescan from 32 bit binaries when I run it I get the
following:

bash-2.05b$ ./vuescan
*** glibc detected *** double free or corruption (out): 0x5556f1ac ***
Aborted

I contacted the author of the software and he thinks it is a glibc problem.

Reproducible: Always
Steps to Reproduce:
1. Download and unpack the vuescan tarball
2. Install 32 versions of libubs and libregmgr
3. try to run Vuescan with ./vuescan

Actual Results:  
bash-2.05b$ ./vuescan
*** glibc detected *** double free or corruption (out): 0x5556f1ac ***
Aborted

Expected Results:  
Vuescan should run.

This is not a glibc problem. It's a bug in vuescan, glibc just refused to
continue when it detected it... You can compile glibc with this check
disabled...

Indeed.  Not a glibc problem and not a problem with a supported package as far
as I can tell.

OK I found some more info on this error message.  The behavior of glibc can be
controlled with the emvironment variable MALLOC_CHECK_ When set to 0 it
disables the checking.  When I do that vuescan segfualts.  When I set it to
1glibc give a beter error message and say there is an invalid pointer.  So this
is a problem with vuescan.  Thanks for you help.
