Including JS support on my project would enable people to leverage exiting "proven" technologies which would make for easier/allowable for adoption in working groups / houses where selection of language is restricted to language of the day :-) Taking this statment and applying this across the board, it would be an easier sell for adoption of FPC/Lazarus with JIT support.

Re: [fpc-pascal] help with synapse mime routines...
Hi Waldo, I have now got the units so I can build and test your code properly. The reason you are getting the exception is that when you free m1 at line 66 you are not freeing the m1 you created at line 44, but the subpart belonging to m. This means that when you finally free m it is trying to free all the objects (mime parts) that it owns including the one you already freed at line 66. If you declare an m2 and use it at line 49 and 50 instead of the m1 all will be well. You have to watch out for objects that are owned by other objects or horrible things will happen!

It was a matter of passing the right parameters to as and ld which required creating hook scripts (actually programs), and using the appropriate binutils, in this case YAGARTO, but CodeSourcery ones should work too (did not test). Luckily, Benjamin Rosseaux helped me with this or I've would have been stuck at for longer. For gnu as I've passed the following parameters in the as hookscript '-march=armv6 -meabi=5' and of course when compiling the crosscompiler and programs the '-CpARMv6 -CfSOFT' parameters need to be passed to fpc.

They are however somewhere to start. 1 In line 63 you are checking to see if m1 is nil to see if the object has already been freed. This will not work as Free does not set the var to nil. Use FreeAndNil(m1) instead to acheive that. yes, that was a flailing attempt to try to bypass the free that apparently shouldn't be... i'll remove that... or, i think i see what you are saying... if i use freeandnil instead of the current m1.free, then the nil test might work and show me that the object is really already gone... i'll try that in addition to the below... 2 In line 49 you are assigning m1 := m.GetSubPart(MyPart - 1) so when you go to free m1, expecting to free the m1 created in line 44, you are in fact freeing the result from the GetSubPart function. right... i'm thinking that m1 should contain only the indicated MIME part from m... ahhh! so what you are saying is that i do not need to explicitly create m1 before assigning m.GetSubPart to it... hummm... but then i have to wonder why it works the first time and not the second? the process does show the proper mime parts, one text/plain and the other text/html... i think i'll manually add a third part to the test message i'm processing and see if i still get the failure on the second one or if it then moves to the third one... i'll do this in addition to testing the above possibility... You have lost the reference you had to the original TMimePart created at line 44. Declare and use say m2 to fix this one. i think the above is one of the main clues... i'll try it out and see what happens...

Re: [fpc-pascal] help with synapse mime routines...
Waldo, You are assigning an OnWalkPart hook procedure to the m1 mimepart you have created, not the mimepart you actually end up freeing. It does not look like the tc.ph procedure is called from the m1 mimeparts (which is what I would expect). If you do need to use the tc.ph on the individual m1 parts, it will need to be setup after m1 := m.GetSubPart(MyPart - 1); The code does not actually use the first m1 so it could be removed including the try finally and the free code. You will also need to remove the m1 := m.GetSubPart(MyPart - 1) line too. The reason that it works the first time is that when you enter the loop m1 is valid. you then set the hook proc up even though this is not the m1 you actually end up using. You then assign a new mimepart to m1, use it and free it at the end of the loop. Second time through, m1 refers to the mimepart for the first sub part which you just freed at the end of the loop and you attempt to use that mimpart to set the hook again but as it has already been freed you get the exception. I think I have that right. I am working from memory now as I do not have the code before me.
