Problem Executing Application Beginning at gcc Version 4.1.3

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




I have an application which compiles cleanly (on i386 Linux using options -g -O2 -pedantic -I../include -Wall `pkg-config --cflags gtk+-2.0`) and executes cleanly using gcc versions 4.1.2 and earlier (I've tried 3.4.1, 4.0.2 & 4.1.2).

But starting with version 4.1.3 (I've tried 4.1.3 & 4.2.1) my application compiles cleanly but does not execute properly. I'm having a very difficult time trying to pinpoint the exact cause. The change in execution is subtle but affects the same area of the application everytime.

I've tried to locate a CHANGES file for 4.1.3 to no avail. Can someone point me to one? That may give me some insight.

Also, I see on http://gcc.gnu.org/ that it indicates the latest version in the 4.1.x series is 4.1.2. Is that correct or in error?

Thanks for any help.
