Created attachment 466764 [details, diff] Fix buffer overflow when writing TIOS file header Both beta7 and beta8 versions of dev-embedded/tigcc segfault when writing the final TIOS executable. This seems to be the same issue mentioned in bug 337059 resurfacing. I believe the patch included in that bug would cause invalid files to be written. I'm attaching a similar patch which seems to fix the issue. Adding '-D_FORTIFY_SOURCE=1' to CFLAGS when building also works as a work around.
