[Mplapack-devel] uninitialised value on iMlaenv1

[Makoto Y. <Mak...@is...>]

Hi,

I found an unstable execution of Rgesv as the following message.

==22859== Conditional jump or move depends on uninitialised value(s)
==22859==    at 0x804B064: iMlaenv1(char const*, char const*, int, int, int, int) (iMlaenv.cpp:89)
==22859==    by 0x804B1DA: iMlaenv(int, char const*, char const*, int, int, int, int) (iMlaenv.cpp:240)
==22859==    by 0x804A9D3: Rgetrf(int, int, __gmp_expr<__gmpf_value, __gmpf_value>*, int, int*, int*) (Rgetrf.cpp:94)
==22859==    by 0x804A2D6: Rgesv(int, int, __gmp_expr<__gmpf_value, __gmpf_value>*, int, int*, __gmp_expr<__gmpf_value, __gmpf_value>*, int, int*) (Rgesv.cpp:91)

The variable Mlaname might is not set correctly in Rgetrf.cpp.
  nb = iMlaenv(1, "Rgetrf", " ", m, n, -1, -1);
The first argument should be 'char const*'. However, the passed argument
is numeric.

I guess the callings of iMlaenv are inconsistent the arguments.

Best,
