Crashing g_string_sprintf when printing invalid floats. gtk+-1.2.9 on Linux

["Eric M. Monsler" <emonsler beamreachnetworks com>]

All,

I am seeing a crash, although with GLib error message, when printing a 
floating point number.

The error message is that GLib is unable to allocate -7 bytes.  Which 
seems reasonable enough.

The problem is that the data I am trying to print does not seem to be a 
valid floating point number.  My program needs to be crash-proof in this 
case, as bad data is going to be encountered.  I see that the value that 
is bad is typically something like "6.0245e-44", which is not valid.

The fact that I can read the value means that ddd/gdb is handling it 
properly, but not g_string_sprintf.

Any clues?  Any suggestions as to how to clamp the floating point value? 
 I have tried to do so with comparisons to MAX_FLT and MIN_FLT, without 
success.

As an aside, the problem has never been observed when using the Solaris 
version of the program, just the Linux one.

Thanks in advance,


Eric Monsler
