* [Bug c++/17277] New: [AIX] could not catch an exception when specified -maix64 @ 2004-09-02 3:21 masahiro at kasahara dot ws 2004-09-02 5:10 ` [Bug target/17277] " pinskia at gcc dot gnu dot org ` (5 more replies) 0 siblings, 6 replies; 8+ messages in thread From: masahiro at kasahara dot ws @ 2004-09-02 3:21 UTC (permalink / raw) To: gcc-bugs Exception handling seems completely broken when -maix64 option is specified. I have tried with g++ version 3.4.0, 3.4.1, 3.4.2 20040829 (prerelease) respectively and got the same result. Following is a small test case. cleo% cat throw.cc #include <stdio.h> int main() { try{ throw 1; } catch( int i ) { printf("catch\n"); } return 0; } cleo% g++ -maix32 throw.cc -o throw; ./throw catch cleo% g++ -maix64 throw.cc -o throw; ./throw zsh: segmentation fault (core dumped) ./throw It works fine under -maix32 option, but when we want to compile in 64-bit mode the compiled binary crushes just after throw. I used native ld and as (which are the latest versions). The configure command line is ./configure --enable-languages=c,c++ --disable-nls -- Summary: [AIX] could not catch an exception when specified - maix64 Product: gcc Version: 3.4.2 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: masahiro at kasahara dot ws CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: powerpc-ibm-aix5.2.0.0 GCC host triplet: powerpc-ibm-aix5.2.0.0 GCC target triplet: powerpc-ibm-aix5.2.0.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17277 ^ permalink raw reply [flat|nested] 8+ messages in thread

The code works correctly in 32-bit mode and the algorithm is the same, so the failure is very suspicious. -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed| |1 Priority|P2 |P1 Last reconfirmed|0000-00-00 00:00:00 |2004-09-09 17:09:46 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17277 ^ permalink raw reply [flat|nested] 8+ messages in thread

Btw, a shared lib , compiled with gcc on AIX 7.1, but in C language is also being used. Would you suggest using a lower verion of the gcc compiler what we used? ^ permalink raw reply [flat|nested] 8+ messages in thread
