Firefox gcc4.12 port fails assertion in posix/malloc/superblock.h:272

[tqh]

This is a gcc4.12 build.

I havn't investigated this much yet, it's bt goes thru BPrivate::processHeap::free() which makes me suspect it's a Haiku problem. See screendump from QEMU for bt.

backtrace in QEMU

Just recalled I have 'experimental' change in nsFontMetricsBeOS, so let me investigate it a bit more.

The assert in question would be interesting, but usually, when an assertion fails in the allocator, it's a memory corruption problem of the user application (or memory freed twice).

probably NS_ConvertUTF16toUTF8 is overwrting the buffer end, you should check that

My experimental code was ofc wrong. Now it works: http://hem.bredband.net/b143824/gcc4_firefox.png

Oh, do close this bug.
