Finally, a C testcase:
void
wb (_Complex double jh)
{
_Complex double af = 0.0;
do
{
af += jh;
}
while (af != 0.0);
}
_Complex double
o6 (void)
{
_Complex double ba = 0.0;
for (;;)
{
wb (ba);
ba = 1.0;
}
return ba;
}
% gcc-11.0.0 -O1 -fanalyzer -c nzttegjf.c
during IPA pass: analyzer
nzttegjf.c: In function 'wb':
