Bug 228889 – [ICE/4.3] building e2fsprogs fails with gcc-4.3.1 ICE with -fipa-pta -O2

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Nico R. 2008-06-22 12:44:19 UTC]

I tried to emerge sys-fs/e2fsprogs-1.40.9 with gcc-4.3.1 and ‘-fipa-pta’ in CFLAGS. This resulted in an ICE for lib/ext2fs/tdb.c.

I’m going to attach my reduced testcase.

Created attachment 157999 [details]
Preprocessed source with reduced testcase for showing gcc-4.3.1 -fipa-pta ICE.

Reduced testcase. Compile with

  LC_ALL=POSIX gcc -O2 -march=i686 -fipa-pta -c testcase.i -v

-fipa-pta doesnt affect code generation, so it doesnt make sense to use it.  upstream is aware of the issues though and is banging away on them.
