Hi everybody,

 

Seems, I have a trouble with function free() in libc. In my app I use several = different libraries (MGUI, pmcom, grx20, ctx2jpg) and sometimes it GPFs on me = (General Protection Fault in RMCB at eip=3D10cf; … = error=3D00a4)

Investigating the call frame traceback EIPs, I found that it is always function = free(), who causes the exception, called from within on of the libraries (MGUI). Particularly, this line of code inside = it:

…

<_free + 0xaa > mov %ecx, %ebx

…

 

According to the exception info DJGPP shows, ecx =3D  00000000 at this = moment.

Does anybody know what may be the problem? Maybe the different libraries I am = using are compiled with different versions of = libc?

 

Any help is greatly appreciated.

 

Alex
