I guess this is a general PHP problem. A segmentation fault and the
zend_mm_heap message basically means that PHP itself crashed. This is
something that should not happen and very likely a "simple" bug in the
C-code of PHP.

Since I could not reproduce the problem so far we'd definitely need to
pinpoint the code section causing the error. But I know from
experience that this is not trivial with a PHP segmentation fault.

What you could try if you know PHP a bit is to add some horde log
message in the viewer code of IMP to further pinpoint the error
location.

The other option is probably to wait for the next PHP version but I
don't know if thats an option.

Cheers,

Gunnar
