Signal handler tests fail on ARM #256
Description
When running make check on ARM. Signal handler test fails. The signal:
'SIGFPE' should appear in the output
The problem is that SIGFPE is not generated on ARM
I've tried to replace division by 0 with explicit raise(SIGFPE) but with no succes. For some reson the stacktrace misses the function name.
