How else can I explain this display from GDB: (gdb) prow y=0 x=0 pwid=673 a+d=12+4=16 phys=12+4=16 vis=16 used=(LMargin=0,Text=84,RMargin=0) Hash=263825844 start=0 end=0 ENA MODEL ? MODEL says that this row has its mode_line_p flag set. Just to be sure, I ran the recipe again under GDB, setting a breakpoint inside verify_row_hash thusly: (gdb) break verify_row_hash if row->mode_line_p != 0 and sure enough, it breaks as soon as I turn on linum-mode, with ROW that shows the glyphs in the mode line. > Without interprocedural analysis the compiler cannot know > that `verify_row_hash' does not alter row->enabled_p, so it cannot > change the evaluation order. I don't know. Maybe GCC does perform such an analysis. Or maybe it decides that the result of this comparison in verify_row_hash: row->hash == row_hash (row) will not change even if row_hash does modify its argument ROW. Or maybe it's a bug in GCC.

But, I haven't made the pretest tag yet---will wait. Thanks. The bug is fixed in revision 106561. It was simply wrong to try to verify rows' hash values at that spot, because the code immediately before that reallocates the glyph arrays, so the contents of a glyph row could be complete garbage. Therefore, I removed the assertion. I'm amazed that this assertion didn't trigger until now. I guess too few people compile with asserts. Or maybe most calls to adjust_glyph_matrix don't really reallocate, since display margins are a relatively rarely used feature. Sorry about this, it was a shameful thinko on my part to introduce that assertion in the first place.

I'm confused about that part.  I discovered the bug using the binary build that came from  http://alpha.gnu.org/gnu/emacs/windows/.  Isn't this where most people would get their copy of Emacs 24?  Wasn't it compiled with asserts?

You might want to add another option: configure --enable-checking=xasserts to enable asserts, it's easier to enable checks when one does not have to edit files.
