Hi,
I am trying to build m4 package but its hanging during testcase validation
Package details
m4 1.4.19
Machine details
operating system: AIX/PPC
oslevel: 7.1.0.0
what is the issue:
one of the testcase is hanging
hanged after this
PASS: test-sigsegv-catch-segv1
PASS: test-sigsegv-catch-segv2
PASS: test-sigsegv-catch-stackoverflow1
ps -ef output:
root 11010342 7078448 0 05:44:31 pts/0 0:00 /bin/sh
../build-aux/test-driver --test-name test-sigsegv-catch-stackoverflow2
--log-file test-sigsegv-catch-stackoverflow2.log --trs-file

root 11927964 11010342 61 05:44:31 pts/0 12:57
./test-sigsegv-catch-stackoverflow2
If I run this testcase manually its working but if we run it with all test
cases then its hanging
