Bug 16463 – emerge prelink segfaults in testsuites

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gábor Farkas 2003-02-27 06:03:04 UTC]

when emerging prelink on a ~x86 up-to-date computer, it segfault when doing the test in the 
testsuite subdir. 
i went into the compile folder , and looked into 1 of the tests ( all tests fail with segfault ): 
"../src/prelink -c ./prelink.conf -C ./prelink.cache --ld-library-path=. --dynamic-linker=./ld-linux.so.2 
-vm ./reloc1" 
this segfaults. 
 
i manually unpacked the prelink package and did a configure --enable-debug=3(i don't know how to 
do that with emerge), make, make check, 
which fails of course with segfault 
 
gdb outputs:
