- Subject: setjmp()/longjmp() bug on h8300-hms
Hello,
The following is a bug report for newlib-1.10.0 on h8300-hms target.
setjmp()/longjmp() always return 16-bit value, so problem is occurred when
compiling with -mint32 flag.
Now my program is working fine after I applied the patch below.
Thank you,
Ryo Tsuruta <ryo@kitanet.ne.jp>
