Description:
The convert command in imagemagick 7.1.1.7 reports IOT instruction errors when converting a png file to pdf format. A quick search in imagemagick's bugzilla doesn't find anything relevant to this issue, so I wonder if maybe something is wrong with the package. A dumped core file is attached.

Additional info:
* package version(s)
imagemagick 7.1.1.7

* system info
CPU: i7-8700
kernel: 6.2.11-zen1-1-zen

Steps to reproduce:
1. Install imagemagick 7.1.1.7
2. Convert a png file to a pdf file by command
```
convert cifib.png -resize 100% cifib.pdf
```
   core.convert.1000.55358a649cc... (553.4 KiB)

Update: convert command in imagemagick 7.1.1.6 works.

Cannot repro. Converting a png to pdf using your command line works fine in the general case.

PS: core files are clunky and very inconvenient to work with. The preferred method these days is to generate a backtrace with debug symbols as per [1].
i.e.
$ coredumpctl gdb (then answer y when it asks "Enable debuginfod for this session?")

This version was released less than 24 hours ago, it is completely to be expected that nobody has reported the issue yet. Please report it upstream and, if possible, attach the affected file, since the issue seems to be specific for that file.

Yes, Antonio, you are right. I have done lots of experiments and confirmed that a png file containing specific mathematical symbols(in this case, it is the integral symbol) and exported by the latest draw.io desktop application at 200% zoom could trigger this runtime error. And really thanks Toolybird for the quick testing and telling me the correct way to collect debug info. I will report this issue to the upstream.
