>Release:        gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
>Organization:
>Environment:
RH 7.1 on AMD thunderbird, intel PIII mobile, AMD athlon
>Description:
Only gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
 does not crash, all more recent versions seems to be flawed. Compiler crashes on anonymous union, like the one included. Can be helped by naming the union after which compiler performs flawlessly.
>How-To-Repeat:
Not quite sure, the union in the test is included in a boundschecking class for our memory manager.
>Fix:
Change from anonymous union to named. union { int a; char b[4];} polka; polka.a=0xDEADFACE; compiles just fine.
