[fpc-devel] 3.3.1 Access violation during compile

[Martin Frb]

My 3.3.1 build is from the 27th June.
However the error did happened with the previous build too. (That is 
according to error msg, I did not compare the trace).

During a build of the Lazarus IDE, ppu files from the previous build 
still in place. Just a handful of source files changed.

There is no pattern to what needs to change.
But the error seems to be bound to a handful of locations (actually, not 
really checked, but I do notice it happens always in the same few units 
/ not sure of the pattern which one it happens in).

In the below case, it is the first function in the "implementation" 
section. ( ide\sourcefilemanager.pas(311,1) )
The function itself has no reference to any of the changed units.
