Hi, I found a memory allocation failure in parseSWF_DEFINESCENEANDFRAMEDATA, util/parser.c:3525,  in the latest version of libming.

Here is the reproducing command:
`./swftophp ./POC2`
[POC2.zip](https://github.com/libming/libming/files/10109788/POC2.zip)

Here is the reproduce trace reported by ASAN:
