Hi there,
I'm using as3compile from 0.9.2 to build swfupload for the debian repo.
Lately i got a bugreport that it segfaults on i386 architecture while
compiling.
This error does not occur on amd64 architecture.
This is, what the compiler says:
----
cd Flash && as3compile -M SWFUpload -T 9 -X 300 -Y 300 -r 15 SWFUpload.as -o
../tmp/swfupload.swf
SWFUpload.as:38:3: warning: function main uses forward or outer block
variable
references (SWFUpload): switching into compatibility mode
SWFUpload.as:925:3: warning: function GetFile uses forward or outer block
variable references (file): switching into compatibility mode
SWFUpload.as:1295:3: warning: function ReturnUploadStart uses forward or

block variable references (message): switching into compatibility mode
SWFUpload.as:1406:3: warning: function BuildRequest uses forward or
outer block
variable references (key): switching into compatibility mode
Segmentation fault (core dumped)
make: *** [build] Error 139
----
Looking in the backtrace of gdb says:
----
Core was generated by `as3compile -M SWFUpload -T 9 -X 300 -Y 300 -r 15
SWFUpload.as -o ../tmp/swfuplo'.

----
It fails on some "substr" in file "FileItem.as".
I searched for it and there is only one "substr" in this file:
----
return "$" + ("0000" +
arguments[0].charCodeAt(0).toString(16)).substr(-4, 4);
----
Changing this to
----
var tmp: String = ("0000" + arguments[0].charCodeAt(0).toString(16));
return "$" + tmp.substr(-4, 4);
----
solves the segfault.
Line 1194 of lib/q.c is
----
unsigned int ohash = h->key_type->hash(key);
----
Is there a fix for this?
