Hi
We are using embedded python in a C++ application
We are seeing memory corruption with a number of OVL, OVF errors in mpatrol
with PyMarshal_ReadObjectFromString on the stack
Each stack trace has the following final 5 functions:
0xFDEA7008 __big_float_times_power+2268
0xFDEA8E34 __decimal_to_binary_fraction+156
0xFDEA9160 __decimal_to_unpacked+460
0xFDEAA5F0 decimal_to_double+572
0xFDEB4FC8 strtod+136
A sample full stack trace is given below.
Any suggestions as to how to fix appreciated.
We are using python 2.2.1
swig 1.1
