Package: rmagic
Version: 2.21-4
Severity: normal
Tags: patch
Hi,
rmagic fails with the current libgd. I don't have the exact error
message here anymore, but it was something like:
* libgd: a memory allocation (silently) failed because there was a
multiplicator 0
* in the perl module: new GD::Image(0,0) failed
* using the *not* created object's can() method causes an crash
A patch is attached. Instead of a 0x0 image create a 1x1 image to get
the supported image formats etc.
