Vlink 0.15b and newer crashes KS1.3

Anybody else noticed that even a simple "hello world"-program crashes KS1.3 if linked with Vlink 0.15b or newer?
It still works with KS2.0 and later and also works in KS1.3 if linked with 0.15a or earlier versions.

My environment is Windows 7. I compiled Vlink WIN32-version with VS2015 nmake, omitting /Dsnprintf=_snprintf from COPTS to get it to compile.

vlink 0.15b changed some critical parts of the linker. Although I worked on it over the whole summer there had still been some issues left. For example:

• Sign-extension of relocation addends, fixed in V0.15c
• Removing zero-bytes at the end of a section, can be disabled with -Z in V0.15d

I guess that both can affect you, especially the section-trimming under Kickstart 1.x, which, unlike OS2.0+, does not automatically delete the uninitialized part of a section.

Solution: Update to vlink V0.15d and use the -Z option when linking for Kickstart 1.x. When you compile with vbcc, using the kick13 config file, or similar, add the -Z option to the -ld, -l2, -ldv, -l2v lines of the config.

(All this will be changed automatically in a future vbcc release, of course.)

Great, -Z solved the crashing. Thanks for fast reply and great tools! Hope that you will keep Kickstart 1.x compability in mind in future also.

For sure! I'm currently working on a m68k-kick13 target for vbcc. So you can work with the original Commodore 1.3 headers and create real 1.3 software.
