[fpc-pascal] Situation with CMEM

Hello Jonas,

Hi, with using CMEM, i found that it must come AFTER pthread unit ,
otherwise progs dont start at all. Seems like it cannot init clib or
something. strace output with that below.
Also, when i put it after, that simple prog with i postet previously crashes before exit. all thread
finished already, but i got RTE 216. Strace have nothing about that .
Thank you for your attention to my problem.


here is strace output :

stat("/usr/lib/zoneinfo/localtime", {st_mode=S_IFREG|0644, st_size=755, ...}) = 0
open("/usr/lib/zoneinfo/localtime", O_RDONLY) = 4
read(4, "TZif\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0\0\0\4\0"..., 44) = 44
brk(0)                                  = 0x80b8850
brk(0x80b8880)                          = 0x80b8880
brk(0x80b9000)                          = 0x80b9000
read(4, 0, 536)                         = -1 EFAULT (Bad address)
read(4, 0, 134)                         = -1 EFAULT (Bad address)
