ok, could reproduce.

the issue appears to be that cmpswap() fails with negative values.

this broke with the new pid allocator.

void
castest(void)
{
	static long xxx = -1;

print("castest!\n");
	assert(xxx == -1);
	assert(cmpswap(&xxx, -1, 518));	// this fails
	assert(xxx == 518);
}

this could be a bug in the linker or with the assembly. i'll write
once i have a fix.
