I attach a short test-case which I have used already to demonstrate
buggy SIGFPE handling on another arch. Usage is documented in the
file. Can you check whether this test case:
On Thecus N2100 (using an IOP32x CPU):
(sid eabi)1587:tbm@all6500: ~/src] ./fputest iffi
Triggering integer SIGFPE: 1/0=(SIGFPE trapped)0
Triggering floating SIGFPE: 1./0.=Triggering floating SIGFPE:
1./0.=Triggering integer SIGFPE: 1/0=(SIGFPE trapped)0
On the Marvell DB-78x00-BP Development Board:
(sid)tbm@mv78x00:~/src$ ./fputest iffi
Contrary to my guess, the SIGILL is not triggered by feenableexcept()
but by setjmp().
The bug is known and is fixed in libc6 2.11 currently in
I just cannot work around this bug in Yorick. In the meantime, I will
just have to go on requesting that Yorick and associated packages be
built on other machines than ancina. Thanks to everybody from the ARM
list for your help.
Best regards, Thibaut.
