(gdb) bt #0 0x28102da3 in getdiskbyname (name=0x5d <Address 0x5d out of bounds>) at /usr/src/lib/libc/gen/disklabel.c:114 #1 0x0805057c in ?? () #2 0x00000005 in ?? () #3 0xbfbfea40 in ?? () #4 0x00000000 in ?? () #5 0xbfbfe9c0 in ?? () #6 0xbfbfe9b8 in ?? () Uhm. Something very bad happens here: Stack corruption and it looks like a stack overflow. The stack limit in libc_r or libpthreads in FreeBSD is 65536 and it is likely that we hit it here. So I experimentally raised the stack size for threaded apps in /usr/src/lib/libpthread/thread/thr_private.h to 128k: #define THR_STACK_DEFAULT 131072 recompiled the pthread lib and now it works. That means it is not save here to place SMALLBUF on the stack. I'll try to convert it to malloc(). Agreed David ?
