CS5 fails to compile large FLAs

Question

There was this problem with CS4 which was solved with an upgrade and now CS5 again fails to compile my larger FLAs. Sad to see the IDE going backwards.

Hi,
I take it you are talking about http://kb2.adobe.com/cps/405/kb405257.html
We now allow you to adjust the JVM heap size manually for larger projects like you can in FlexBuilder/FlashBuilder:
WIN:
1. Quit Flash
2. In a text editor, open the jvm.ini file from the following location:
Windows XP: Hard Disk\Documents and Settings\<user>\Local Settings\Application Data\Adobe\Flash CS5\<language>\Configuration\ActionScript 3.0\jvm.ini
Windows Vista or Windows7: Hard Disk\Users\<user>\AppData\Local\Adobe\Flash CS5\<language>\Configuration\ActionScript 3.0\jvm.ini
(You might need to turn on "show hidden files")
3. Change -Xmx128m to -Xmx256m and save the file.  This line specifies the amount of heap space the core ActionScript 3.0 compiler should allocate for compiling.
4. Relaunch Flash and compile
5. If that doesn't work, try changing the value to 512m
MAC:
1. Quit Flash
2. In a text editor, open the jvm.ini file from the following location:
/Users/<user>/Library/Application Support/Adobe/Flash CS5/<language>/Configuration/ActionScript 3.0/jvm.ini
3. Change -Xmx128m to -Xmx256m and save the file.  This line specifies the amount of heap space the core ActionScript 3.0 compiler should allocate for compiling.
4. Relaunch Flash and compile
5. If that doesn't work, try changing the value to 512m
Since the JVM heap space might be required by other programs as well, you want to be conservative with the amount to allocate.  So try 256 before trying 512.
We are in the process of updating the original tech note.
