Issue #2417 has been updated by John Marino.
Status changed from New to Closed
Two yamcha utilities had bugs in them:
pkemine (tried to free std:cin)
mktrie (tried to free a freed object, also char casting bug)
After fixing these bugs, textproc/cabocha builds fine with rebuild yamcha tools.
fixed in pkgsrc:
Bug #2417: i386-only failure involving nmalloc (ZALLOC_SLAB_MAGIC assert)
Author: John Marino
The yamcha tools build on both platforms. However, they only work on x86_64.
When the yamcha tool pkemine tries to generate a file for cabocha on i386, it core dumps:
#0 _slabfree (ptr=<optimized out>, flags=<optimized out>, rbigp=0x0)
1165 MASSERT(z->z_Magic == ZALLOC_SLAB_MAGIC);
The 4-frame backtrace is here:
The i386 pkemine executable is here:
A packed coredump is here:
The two platforms have different malloc implementations. Why is i386's implementation dumping why x86_64's is happy?
