Truncating stackcalls and line numbers in eventLog.txt #20

When doing fulldebugmode in fastmm5 (4 does as well) and checking for leaks the lines seem to be truncated to a fix length in the memorymanager_eventlog.txt E.G. below 0000000004292815 [FormEmailPropertyViewer.pas][FormEmailPropertyViewer][_ZN23Formemailpropertyviewer22TvwEmailPropertyViewer13UpdateDisplayEv][5 0000000001E3087E [DataEntryUtils.pas][DataEntryUtils][_ZN14Dataentryutils12TEntryReader12GetIsManagedEv][273] 0000000004295080 [FormEmailPropertyViewer.pas][FormEmailPropertyViewer][_ZN23Formemailpropertyviewer22TvwEmailPropertyViewer17DoContainerChangeE 0000000002E6F999 [UViewManager.pas][UViewManager][_ZN12Uviewmanager11TViewerBase16DoContainerEventEPN9Container10TContainerERKN10Dataevents16TDa

Hi Kevin,

I have increased the size of the line buffer from 128 to 224 characters (a 75% increase). FastMM preallocates a fixed size buffer for stack traces, so the line lengths currently have to be limited.

Please let me know whether the maximum line length is now sufficient.

Thanks, Pierre

Thanks Pierre for the quick turnaround it helps a ton. The longest line I am finding so far in Generics at 223 00000000053C05EF [System.Generics.Collections.pas][MetaData][_ZN6System8Generics11Collections6TArray12BinarySearchIPN8Metadata15TMetaDataRecordEEEbPKT_iS8_RiNS_15DelphiInterfaceINS0_8Defaults12IComparer__1IS8_EEEEii][1043]
