Public bug reported:

I reported this bug upstream, including a suggested patch.

https://rt.cpan.org/Public/Bug/Display.html?id=91483

This bug creates problems when running zoneminder-1.25.0-4ubuntu2

Especially when running zmtrigger.pl.

Here is the information from the upstream bug report:

 When munmap is called, this section of code is hit: if(SvTYPE(var) !=
SVt_PV) { croak("variable is not a string"); return; } by adding
additional information to the croak statement, I determined that var is
type 7, SVt_PVMG. This causes munmap failure. I modified the code, see
attached patch file svtype-fix, which seems to fix the problem. I think
that we want to allow everything between SVt_PVMG and SVt_PV to be
accepted as unmap. Here is output from the modified croak call, variable
is not a string: 7 at /usr/share/perl5/ZoneMinder/Memory/Mapped.pm line
115. croak("variable is not a string, type is: %d", SvTYPE(var));
