Hi! I sow something about problem like yours in article
<1991Feb15.110703.18147@watserv1.waterloo.edu> with subject
"Frequently Asked Questions, comp.windows.ms.programmer edition" from
Tom Haapanen:
 
11. Why does compiling a Windows application with emulator floating-point
    cause corrupted code segments when running on a non-87 machine?
 
>>  The emulated floating point tries to used the coprocessor. When it does
    not find one on startup, it patches the code to use the software floating
    point. Patching does however not adapt the code-segment checksum, thus
    the windows debugging version chokes when it horridly founds that some-
    thing terrible must have happened to the code.
    Get rid of it by setting 'EnableSegmentChecksum=0' in the [debug]
    section of WIN.INI; the problem only affects debugging versions of
    Windows.
