[pkg-firebird-general] Bug#840666: firebird3.0: FTBFS on powerpc, segfaults during build

[John Paul Adrian Glaubitz]

Source: firebird3.0
Version: 3.0.1.32609.ds4-6
Severity: serious
Tags: upstream
Justification: fails to build from source
User: debian-powerpc at lists.debian.org
Usertags: powerpc

Hello!

firebird3.0 currently fails to build from source since the gpre
command segfaults during build:

sh -x -c "lockfile -1 /«PKGBUILDDIR»/gen/Release/firebird/bin/build-db.lock && /«PKGBUILDDIR»/gen/Release/firebird/bin/gpre_current -m -z -n /«PKGBUILDDIR»/src/yvalve/blob.epp /«PKGBUILDDIR»/temp/Release/yvalve/blob.cpp; res=\$?; rm -f /«PKGBUILDDIR»/gen/Release/firebird/bin/build-db.lock; exit \$res"
+ lockfile -1 /«PKGBUILDDIR»/gen/Release/firebird/bin/build-db.lock
+ /«PKGBUILDDIR»/gen/Release/firebird/bin/gpre_current -m -z -n /«PKGBUILDDIR»/src/yvalve/blob.epp /«PKGBUILDDIR»/temp/Release/yvalve/blob.cpp
gpre version LI-V3.0.1.32609 Firebird 3.0
Segmentation fault
+ res=139
+ rm -f /«PKGBUILDDIR»/gen/Release/firebird/bin/build-db.lock
+ exit 139

I have done some debugging and from the backtrace it's obvious that
the crash occurs in glibc:

This looks similar to the FTBFS of lua5.3 on powerpc [1] which is
triggered by the use of a version script for the linker and, in
fact, firebird3.0 is using such scripts. Now, this actually reminded
me of another similar problem we had on sparc back then [2] which
is the missing _IO_stdin_used symbol in the version script. lua5.2
was affected by that problem as well and Aurelien Jarno fixed that
by adding that symbol to the version script [3].

I tried the fix from [3] in firebird3.0, but unfortunately it
doesn't help. Currently, I'm out of ideas but it would be great
to see this fixed as this also affects m68k for which I have
added platform support to firebird upstream [4,5].

Thanks,

Adrian
