On building FF for OI I run in core dumps.<br /><br />It seems that this are raised by MOZ_ASSERTION because the JS-engine (spidermonkey) expects that addresses for JS Values are not in the upper memory area:<br /><br />ptr must be a valid user-mode pointer, with the top 16 bits clear<br /><br />The ptr is for example 0xfffffbffef120fb0
so the address is too high in this case. pmap shows the related range as mmap allocated area (anonymous)<br />Related the assertions there was a change in FF68.2<br /><br />In solaris-userland Oracle has placed a patch but only for Sparc: sparc-47bit-VA-space.patch<br />This use a mapfile with<br />RESERVE_SEGMENT spidermonkey_reserve {<br /> VADDR = 0x800000000000;<br /> SIZE = 0xffff7fffffff0000;<br />};<br />Illumos ld don't know the option RESERVE_SEGMENT, but it is for Sparc how I already stated.<br /><br />Do IllumOS use the whole 64bit address space and not only the expected 47bit? Or I am completly wrong here in the maze of physical and virtual address spaces?<br />-- <br signature="separator" />Carsten
