Yes, it was a good one, although somewhat rainy. ;-) >> For the first question - the best way to find exact place of SIGSEGV >> etc. in FPC programs under OS/2 is to compile everything with debug >> information (including RTL, FCL etc.) > > This needs a little more explaining.

Just RTL compilation with debug information is done by running "make debug" in the /rtl/os2 source directory. The same could be done for /packages/base and /fcl. Alternatively, it would be possible to build the whole thing (e.g. including the compiler as well) in usual ZIP files using "make os2zip SNAPSHOT=1 DEBUG=1" in the root directory, but you need to have checkout of the "fpcbuild" SVN repository (just the "fpc" repository is not enough). See the "Build FAQ" (http://www.stack.nl/~marcov/buildfaq.pdf) for other options and additional information. If you find any difficulties, just ask here. >> either run them under (PM)GDB, or to open the generated core file in >> (PM)GDB > > After being used to vp I am still struggeling with gdb :-( But I hope I > will master it eventualy. To be honest, I understand this completely... :-( The support which is available for other FPC platforms is much better (IDE with debugger support), but this is fairly difficult to achieve for OS/2 due to problems with OS/2 gdb version (spawned from GDB version 4.16 ten years ago and never brought up to date - the current GDB version is something like 6.30). Implementation of native debugger emulating the GDB interface would be probably possible, but is a lot of work. I asked Allan about the possibility to get access to VP/2 debugger sources after he announced end of VP life, but he didn't respond to that e-mail, unfortunately. :-( Nevertheless, if you have particular questions regarding (PM)GDB, just ask.
