Package: ltrace Version: 0.7.91~git20230705.8eabf68-2 Severity: normal Control: forwarded -1 https://gitlab.com/cespedes/ltrace/-/issues/22
Dear Maintainer,
Given
#include <math.h>
#include <stdio.h>
int main(int n, char **) {
printf("%d %f\n", n, log(n));
printf("%d %Lf\n", n, logl(n));
}
ltrace ./b $(seq 1000) yields
log(1001.000000) = 6.908755
printf("%d %f\n", 1001, 6.908755) = 14
logl(0.000000) = 0.000000
printf("%d %Lf\n", 1001, 0.000000) = 14
1001 6.908755
1001 6.908755
+++ exited (status 0) +++
even though
/usr/share/ltrace/libm.so.conf:ldouble logl(ldouble);
...actually this looks to be because
etc/libc.so-types.conf:typedef ldouble = double;
...and I tried and failed to add long double support
(this appears much more... convoluted. than long long)
Best,
